I have a PHP file which has the following text:
<div class="small_italic">This is what you´ll use</div>
On one server, it appears as:
This is what you´ll use
And on another, as:
This is what you�ll use
Why would there be a difference and what can I do to make it appear properly (as an apostrophe)?
Note to all (for future reference)
I implemented Gordon's / Gumbo's suggestion, except I implemented it on a server level rather than the application level. Note that (a) I had to restart the Apache server and more importantly, (b) I had to replace the existing "bad data" with the corrected data in the right encoding.
/etc/php.ini
default_charset = "iso-8859-1"
You have to make sure the content is served with the proper character set:
Either send the content with a header that includes
<?php header("Content-Type: text/html; charset=[your charset]"); ?>
or - if the HTTP charset headers don't exist - insert a <META> element into the <head>:
<meta http-equiv="Content-Type" content="text/html; charset=[your charset]" />
Like the attribute name suggests, http-equiv is the equivalent of an HTTP response header and user agents should use them in case the corresponding HTTP headers are not set.
Like Hannes already suggested in the comments to the question, you can look at the headers returned by your webserver to see which encoding it serves. There is likely a discrepancy between the two servers. So change the [your charset] part above to that of the "working" server.
For a more elaborate explanation about the why, see Gumbo's answer.
The display of the REPLACEMENT CHARACTER � (U+FFFD) most likely means that you’re specifying your output to be Unicode but your data isn’t.
In this case, if the ACUTE ACCENT ´ is for example encoded using ISO 8859-1, it’s encoded with the byte sequence 0xB4 as that’s the code point of that character in ISO 8859-1. But that byte sequence is illegal in a Unicode encoding like UTF-8. In that case the replacement character U+FFFD is shown.
So to fix this, make sure that you’re specifying the character encoding properly according to your actual one (or vice versa).
To sum it maybe up a little bit:
Make sure the FILE saved on the web server has the right encoding
Make sure the web server also delivers it with the right encoding
Make sure the HTML meta tags is set to the right encoding
Make sure to use "standard" special chars, i.e. use the ' instead of ´of you want to write something like "Luke Skywalker's code"
For encoding, UTF-8 might be good for you.
If this answer helps, please mark as correct or vote for it. THX
The simple solution is to use ASCII code for special characters.
The value of the apostrophe character in ASCII is ’. Try putting this value in your HTML, and it should work properly for you.
Set your browser's character set to a defined value:
For example,
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
This is probably being caused by the data you're inserting into the page with PHP being in a different character encoding from the page itself (the most common iteration is one being Latin 1 and the other UTF-8).
Check the encoding being used for the page, and for your database. Chances are there will be a mismatch.
Create an .htaccess file in the root directory:
AddDefaultCharset utf-8
AddCharset utf-8 *
<IfModule mod_charset.c>
CharsetSourceEnc utf-8
CharsetDefault utf-8
</IfModule>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

I have some texts in French (containing accented characters such as "é"), stored in a MySQL table whose collation is utf8_unicode_ci (both the table and the columns), that I want to output on an HTML5 page.
The HTML page charset is UTF-8 (< meta charset="utf-8" />) and the PHP files themselves are encoded as "UTF-8 without BOM" (I use Notepad++ on Windows). I use PHP5 to request the database and generate the HTML.
However, on the output page, the special characters (such as "é") appear garbled and are replaced by "�".
When I browse the database (via phpMyAdmin) those same accented characters display just fine.
What am I missing here?
(Note: changing the page encoding (through Firefox's "web developer" menu) to ISO-8859-1 solves the problem... except for the special characters that appears directly in the PHP files, which become now corrupted. But anyway, I'd rather understand why it doesn't work as UTF-8 than changing the encoding without understanding why it works. ^^;)
I experienced that same problem before, and what I did are the following
1) Use notepad++(can almost adapt on any encoding) or eclipse and be sure in to save or open it in UTF-8 without BOM.
2) set the encoding in PHP header, using header('Content-type: text/html; charset=UTF-8');
3) remove any extra spaces on the start and end of my PHP files.
4) set all my table and columns encoding to utf8mb4_general_ci or utf8mb4_unicode_ci via PhpMyAdmin or any mySQL client you have. A comparison of the two encodings are available here
5) set mysql connection charset to UTF-8 (I use PDO for my database connection )
PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"
PDO::MYSQL_ATTR_INIT_COMMAND => "SET CHARACTER SET utf8"
or just execute the SQL queries before fetching any data
6) use a meta tag <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
7) use a certain language code for French
<meta http-equiv="Content-language" content="fr" />
8) change the html element lang attribute to the desired language
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fr" lang="fr">
and will be updating this more because I really had a hard time solving this problem before because I was dealing with Japanese characters in my past projects
9) Some fonts are not available in the client PC, you need to use Google fonts to include it on your CSS
10) Don't end your PHP source file with ?>
NOTE:
but if everything I said above doesn't work, try to adjust your encoding depending on the character-set you really want to display, for me I set everything to SHIFT-JIS to display all my japanese characters and it really works fine. But using UFT-8 must be your priority
This works for me
Make your database utf8_general_ci
Save your files in N++ as UTF-8 without BOM
Put $mysqli->query('SET NAMES utf8'); after the connection to the database in your PHP file
Put < meta charset="utf-8" /> in your HTML-s
Works perfect.
If your php.ini default_charset is not set to UTF-8, you need to use a Content-type to define your data. Apply the following header at the top of your file(s) :
header("Content-type: text/html; charset=utf-8");
If you have still troubles with encoding, the cause may be one of the following:
a database server charset problem (check encoding of your server)
a database client charset problem (check encoding of your connection)
a database table charset problem (check encoding of your table)
a php default encoding problem (check default_encoding parameter in parameters.ini)
a multibyte missconfigured (see mb_string parameters in parameters.ini)
a <form> charset problem (check that it is sent as utf-8)
a <html> charset problem (where no enctype is set in your html file)
a Content-encoding: problem (where the wrong encoding is sent by Apache).
SET NAMES worked for me.
My issue was in one of my editing pages the field with the foreign characters would not display, on the production web pages there was no problem.
I know you already have an answer. That's great. But strangely none of these answers solved my issue. I'd like to share my answer for the benefit of the others who may encounter the same issues.
I also had the same problems as the OP, with regards to French accents in a multi-lingual application.
But I encountered this issue for the first time when I had to pass (French accented) data as segments in AJAX calls.
Yes, we must have the database set to work with UTF8. But the fact that AJAX calls had query strings (in my case segments, since I'm using CodeIgniter), I had to simply encode the French text.
To do this on the client-side, use the Javascript encodeURI() function with your data.
And to reverse it in PHP, just use urldecode($MyStr) where data was received as parameters.
Hope this helps.
Type something full French signs in your (php) file
Save that file as UTF-8
Paste line beneath into your website header
header('Content-Type: text/html; charset=utf-8');
Page (file) should look good.
If looks good go here for mysql behavior after (SET_NAMES).
I am new here, so I apologize if I am doing anything wrong.
I have a form which submits user input onto another page. User is expected to type ä, ö, é, etc... I have placed all of the following in the document:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
header('Content-Type:text/html; charset=UTF-8');
<form action="whatever.php" accept-charset="UTF-8">
I even tried:
ini_set('default_charset', 'UTF-8');
When the other page loads, I need to check what the user input with something like:
if ( $_POST['field'] == $check ) {
...
}
But if he inputs something like 'München', PHP will compare 'München' with 'München' and will never trigger TRUE even though it should. Since it is specified UTF-8 everywhere, I am guessing that the server is converting to something else (Windows-1252 as I read on another thread) because it does not support or is not configured to UTF-8. I am using Apache on a local server before I load into production; I have not changed (and don't know how to) any of the default settings. I've been working on a Windows 7, editing with Notepad++ enconding my files in ANSI. If I bin2hex('München') I get '4dc3bc6e6368656e'.
If I echo $_POST['field']; it displays 'München' correctly.
I have researched everywhere for an explanation, all I find is that I should include those tags/headings I already have.
Any help is much appreciated.
You are facing many different problems at the same, let's start with the simplest one.
Problem 1) You say that echo $_POST['field']; will display it correctly? What do you mean with "display"? It can be displayed correctly in two cases:
either the field is in UTF-8 and your page has been declared as UTF-8 and the browser is displaying it as UTF-8 or,
the field is in Latin-1 and the browser has decided (through the auto-detection heuristics) that your page is in Latin-1.
So, the fact that echo $_POST['field']; is correct tells you nothing.
Problem 2) You are using
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
header('Content-Type:text/html; charset=UTF-8');
Is this PHP code? If it is, it will be an error because the header must be set before sending out any byte. If you do this you will not set the Content-Type header and PHP should generate a warning.
Problem 3) You are using
<form action="whatever.php" accept-charset="UTF-8">
Some browsers (IE, mostly) ignore accept-charset if they can coerce the data to be sent in ASCII or ISO Latin-1. So the data will be in UTF-8 and declared as ISO Latin-1 or ISO Latin-1 and sent as ISO Latin-1 (but this second case is not your case).
Have a look at https://stackoverflow.com/a/8547004/449288 to see how to solve this problem.
Problem 4) Which strings are you comparing? For example, if you have
$city = "München"
$_POST['city'] == $city
The result of this code will depend on the encoding of the PHP file. If the file is encoded in ISO Latin-1 and the $_POST correctly contains UTF-8 data, the == will compare different bytes and will return false.
Another solution that may be helpful is in Apache, you can place a directive in your configuration file (httpd.conf) or .htacess called AddDefaultCharset. It looks like this:
AddDefaultCharset utf-8
http://httpd.apache.org/docs/2.0/mod/core.html#adddefaultcharset
That will override any other default charsets.
I changed "mbstring.detect_order = pass" in my php.ini file and i worked
I've used Unicode characters in my forms and file many times. I had not any problem up to now.
Try to do these steps and check the result:
Remove header('Content-Type:text/html; charset=UTF-8'); from your HTML form codes.
Use your form just like <form action="whatever.php"> without accept-charset="UTF-8". (It's better to insert the method of sending data in your form tag).
In target page (whatever.php), insert again <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> in a <head> tag.
I always did my project like what I mentioned here and I did not have any problem with Unicode strings.
This is due to the character encoding of the PHP file(s).
The hardcoded München is stored with the character encoding of the source file(s), in this case ANSI and when that value is compared to the UTF-8 encoded value provided in the $_POST variable, the two will, quite naturally, differ.
The solution to your problem is one of:
Serve and process content with the same encoding as that of the source file(s), in this case likely to be windows-1252.
This would, for starters, include changing the content="text/html; charset=UTF-8" to content="text/html; charset=windows-1252" whenever serving HTML data.
Avoid all hardcoded values that could be affected by character encoding issues between UTF-8 and windows-1252, more or less only hardcode values that only includes English letters and numbers.
Any UTF-8 values would have to be read from a source that ensures they are UTF-8 encoded (for instance a database set to use UTF-8 as storage encoding as well as connection encoding).
Wrap all hardcoded assignments in utf8_encode(), for instance $value = utf8_encode ('München');
Change the encoding of the source file(s) to UTF-8.
This can be accomplished in any number of ways, a decent text editor will be able to do it or the outstanding libiconv can be used, especially for batch processing.
Either solution 1 or 4 would be my preferred solution, especially if multiple people are involved in the project.
As a side-note, some text editors (notably Notepad++) has the option of using either UTF-8 or UTF-8 without BOM. The BOM (Byte Order Mark) is pointless in UTF-8 and will cause problems when writing headers in PHP (most often when doing a redirect). This is because the BOM is right in front of the initial <?php, causing the server to send the BOM just as it would had there been any other character in front. The difference is you'd note a character in front, but the BOM isn't displayed.
Rule of thumb: Always use UTF-8 without BOM.
in PhpMyAdmin it shows up as 'Petite-Réserve" but when i echo it to a webpage it shows as "Petite-R�serve" MyISAM latin1_swedish_ci is the database encoding and <!DOCTYPE html><head><meta http-equiv="content-type" content="text/html; charset=utf-8" /> is at the top of the page. Not sure how to fix this. I'm allowing users to input text and users are French and English. I'm using Google Chrome and it shows up as a question mark in a triangle. Any ideas?
You need to use the right content-type on the page - since you are outputting latin1 (as defined in your database), try this:
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
iso-8859-1 is the encoding name for latin1.
If you use a different encoding to output data to that is has been saved in, you have to encode or decode the data beforehand. Try
utf8_encode($value);
in this case.
Alternatively, change the encoding of your HTML to iso-8859-1.
Often best to decide on one charset and not to mix them. If you mix them you will have to convert between them. mbstring can help there. Best to switch your database to UTF-8. It is more flexible then the latin variations.
Check the HTTP response headers sent by your webserver. One of the headers might include the content-type, and that value in your http headers might not match the UTF-8 encoding declaration you've got in HTML.
I have looked around and can't seem to find a solution so here it is.
I have the following code:
$file = "adhddrugs.xml";
$xmlstr = simplexml_load_file($file);
echo $xmlstr->report_description;
This is the simple version, but even trying this any hyphens r apostrophes are turned into: ^a (euro sign) trademark sign.
Things I have tried are:
echo = (string)$xmlstr->report_description; /* did not work */
echo = addslashes($xmlstr->report_description); /* yes I know this doesnt work with hyphens, was mainly trying to see if I could escape the apostrophes */
echo = addslashes((string)$xmlstr->report_description); /* did not work */
also htmlspecial(again i know does not work with hyphens), htmlentities, and a few other tricks.
Now the situation is I am getting the XML files from a feed so I cannot change them, but they are pretty standard. The text with the hyphens etc are encapsulated in a cdata tag and encoding is UTF-8. If I check the source I am shown the hyphens and apostrophes in the source.
Now just to see if the encoding was off or mislabeled or something else weird, I tried to view the raw XML file and sure enough it is displayed correctly.
I am sure that in my rush to find the answer I have overlooked something simple and the fact that this is really the first time I have ever used SimpleXML I am missing a very simple solution. Just don't dock me for it I really did try and find the answer on my own.
Thanks again.
This is the simple version, but even
trying this any hyphens apostrophes
are turned into: ^a (euro sign)
trademark sign.
This is caused by incorrect charset guessing (and possibly recoding).
If a text contains a "curly apostrophe" = "Right single quotation mark" = U+2019 character, saving it in UTF-8 encoding results in bytes 0xE2 0x80 0x99. If the same file is then read again assuming its charset is windows-1252, the byte stream of the apostrophe character (0xE2 0x80 0x99) is interpreted as characters ’ (=small "a" with circumflex, euro sign, trademark sign). Again if this incorrectly interpreted text is saved as UTF-8 the original character results in byte stream 0xC3 0xA2 0xE2 0x82 0xAC 0xE2 0x84 0xA2
Summary: Your original data is UTF-8 and some part of your code that reads the data assumes it is windows-1252 (or ISO-8859-1, which is usually actually treated as windows-1252). A probable reason for this charset assumption is that default charset for HTTP is ISO-8859-1. 'When no explicit charset parameter is provided by the sender, media subtypes of the "text" type are defined to have a default charset value of "ISO-8859-1" when received via HTTP.' Source: RFC 2616, Hypertext Transfer Protocol -- HTTP/1.1
PS. this is a very common problem. Just do a Google or Bing search with query doesn’t -doesn't and you'll see many pages with this same encoding error.
Do you know the document's character set?
You could do header('Content-Type: text/html; charset=utf-8'); before any content is printed, if you havent already.
Make sure you have set up SimpleXML to use UTF-8 too.
Be sure that all the entities are encoded using hex notation, not HTML entities.
Also maybe:
$string = html_entity_decode($string, ENT_QUOTES, "utf-8");
will help.
This is a symptom of declaring an incorrect character set in the <head> section of your page (or not declaring and using default character set without accents and special characters).
This does the trick for latin languages.
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
For TOTAL NEWBIES, html pages for browsers have a basic layout, with a HEAD or HEADER which serves to tell the browser some basic stuff about the page, as well as preload some scripts that the page will use to achieve its functionality(ies).
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
Hello world
</body>
</html>
if the <head> section is omitted, html will use defaults (take some things for granted - like using the northamerican character set, which does NOT include many accented letters, whch show up as "weird characters".
I'm using Kohana 3, which has full support for Unicode.
I have this as the first child of my <head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
The Unicode character I am inserting into is é as in Café.
However, I am getting the triangle with a ? (as in could not decode character).
As far as I can tell in my own code, I am not doing any string manipulation on the text.
In fact, I have placed the accent straight into a view's PHP file and it is still not working.
I copied the character from this page: http://www.fileformat.info/info/unicode/char/00e9/index.htm
I've only just started examining PHP's Unicode limitations, so I could be doing something horribly wrong.
So, how do I display this character? Do I need to resort to the HTML entity?
Update
So this works
Caf<?php echo html_entity_decode('é', ENT_NOQUOTES, 'UTF-8'); ?>
Why does that work? If I copy the output accented e from that script and insert it into my document, it doesn't work.
View the http headers. You should see something like
Content-Type: text/html; charset=UTF-8
Browsers don't pay much attention to meta tags, if there was a real http header stating a different encoding.
update
Whatcha get from this?
echo bin2hex('é');
echo chr(0xc3) . chr(0xa9);
You should get c3a9é, otherwise I'd say file encoding issue.
I guess, you see �, the replacement character for invalid UTF-8 byte sequences. Your text is not UTF-8 encoded. Check your editor’s settings to control the encoding of the PHP file.
If you’re not sure about the encoding of your sources, you can enforce UTF-8 compatibilty as described here (German text): Force UTF-8.
You should never need entities except the basic ones.
