i have problems with encoding when using json and ajax.
chrome and ie encode umlauts as unicode when jsonifying, firefox and safari returning those utf-8 escaped umlauts like ¼Ã.
where is the best place to give all the same encoding?
js / php-get or by writing them to the database.
and i think the next trouble is, when i reload the utf-8 encoded stuff from the db, and write them to the browser and then rewrite them to the db, again via ajax-request a get a real chaos?
can i avoid the chaous? can i handle the encoding in an easy way?
pls. help :-)
very important is to also provide security
You must set everything to UTF-8, this means :
Database collation
Table collation
Field collation
Your coding software (example notepad++) encryption.
Had a similar problem. Maybe you are actually interpreting encoding the wrong way, clientwise. Try setting the frontend encoding before your queries.
<?php
$connection = pg_pconnect("dbname=data");
pg_set_client_encoding($connection, "encoding goes here"); //check enconding aletrnatives on PostgreSQL
$result = pg_query($connection, "SELECT whatever FROM wherever");
//and so on...
?>
I'm a newbie, but it may help. Also won't affect security in anyway if you are already protected against db injection.
Cheers

I am currently moving blog posts from wordpress to drupal. however after moving it
some of the text is not being displayed correctly.
wordpress is displaying :
When it hasn’t (html code is <h2>When it hasn’t</h2>)
Drupal is displaying :
When it hasn’t (html code is <h2>When it hasn’t</h2>)
In the wordpress and drupal db the value is correct. The source is the same.
<h2>When it hasn’t</h2>
I did a search and found many options. None of them helped.
Below are the ones I have done and checked.
1) I double checked that utf-8 is the character encoing in drupal and wp.
I also made a simple test.php file to check nothing else was coming in the way
and it still did not display correctly.
2) I made sure when we take a mysqldump and upload to drupal utf-8
is used.
3) I also made sure the .php file is in utf-8 when saved.
4) I changed the encoding type in chrome for every option available and nothing
displayed it correctly.
5) I also used php functions to recode it but they did not work.
$value2="<h2>When it hasn’t</h2>";
$out = recode_string('..utf-8', $value2);
//output - When it hasnt
$out2= mb_convert_encoding($value2,'UTF-8', "UTF-8");
// output - When it hasn’t
$out3= #iconv('UTF-8', 'utf-8', $value2);
// output - When it hasn’t
I have ran out of options now and I am stuck. Please help
You say the text in both databases is correct, but actually this doesn't mean too much: to viewing the content of a record you must use some client, and quite a few transformations may happen depending on how the text is rendered so you can read it.
So only two things matters:
the encoding of the column
the encoding of the HTML page returned by Drupal
Since your page outputs ’ (in CP1252 is xE2x80x99) for ’ (Unicode U+2019, UTF-8 is 0xE28099) I guess the column is indeed UTF-8, however there's someone between the database and the browser who thinks the text is CP1252. This is what you have to check:
If using MySQL, the connection encoding must be UTF-8 so that what you have in your PHP script is UTF-8 text. You can use SET NAMES 'UTF-8'. Note that if you don't need the Unicode set, you can even use CP1252: the only important thing is that you know the encoding, since PHP strings are just byte arrays.
Explicitely define the response encoding in the HTTP Content-Type header. I mean, configure Drupal to call header('Content-Type: text/html; charset=utf-8');
If the HTTP response encoding is different than the one used for the text retrieved from the db, transcode the query result accordingly
I am trying to translate a English website to Persian. problems i was facing was :
website were loading in Latin Unicode, so I had to change the charset to utf-8 so contents show correctly in Persian
data in MySQL database are not correctly shown in website probably cause of the Unicode problem
What I have done:
<?php ini_set('default_charset','utf-8'); header('Content-type: text/html; charset=utf-8'); ?>
by this , problem #1 fixed
but for problem number 2 i still facing the issue, although i have altered the tables to use utf 8 , but problem still persists. I gladly like to see how anyone can help me with this.

Sorry, my reply wasn't clear enough. I was almost sleep. The databases are empty, so I don't have to convert anything, but when I am inserting data into them, the data doesn't appear correctly. BTW, I'm not good with php or mysql; I am reading these articles and suggestions for hours and I'm just getting more confused. Can you just tell me where should I enter the code and what code,
$link = mysql_connect("localhost","UserName","Password") or die(mysql_error());
mysql_set_charset("utf8",$link);
mysql_select_db("DataBase Name") or die(mysql_error());
I guess the thing I found out from these articles is to add the mysql_set_charset("utf8",$link) part to the above code while the server tries to connect to db, but I have tried that and its not working. My website uses includes so thats like this:
include("../../config/config.php");
$connect = mysql_connect("$db_host", "$db_user", "$db_pass")or die(mysql_error());
mysql_set_charset("utf8",$link);
Assuming you've correctly converted the data in your tables to UTF-8 (just changing the character set is not enough), it sounds like you might be having problems with the connection not being set up as UTF-8. Have a look at SET NAMES, and more specifically this question.
If you're not sure you've converted your data to UTF-8, I'd have a look at this question as well as this Wordpress article and make sure you've followed the steps.
I'm working with UTF-8 encoding in PHP and I keep managing to get the output just as I want it. And then without anything happening with the code, the output all of a sudden changes.
Previously I was getting hebrew output. Now I'm getting "&&&&&".
Any ideas what might be causing this?
These are most common problems:
Your editor that you’re creating the PHP/HTML files in
The web browser you are viewing your site through
Your PHP web application running on the web server
The MySQL database
Anywhere else external you’re reading/writing data from (memcached, APIs, RSS feeds, etc)
And few things you can try:
Configuring your editor
Ensure that your text editor, IDE or whatever you’re writing the PHP code in saves your files in UTF-8 format. Your FTP client, scp, SFTP client doesn’t need any special UTF-8 setting.
Making sure that web browsers know to use UTF-8
To make sure your users’ browsers all know to read/write all data as UTF-8 you can set this in two places.
The content-type tag
Ensure the content-type META header specifies UTF-8 as the character set like this:
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=UTF-8">
The HTTP response headers
Make sure that the Content-Type response header also specifies UTF-8 as the character-set like this:
ini_set('default_charset', 'utf-8')
Configuring the MySQL Connection
Now you know that all of the data you’re receiving from the users is in UTF-8 format we need to configure the client connection between the PHP and the MySQL database.
There’s a generic way of doing by simply executing the MySQL query:
SET NAMES utf8;
…and depending on which client/driver you’re using there are helper functions to do this more easily instead:
With the built in mysql functions
mysql_set_charset('utf8', $link);
With MySQLi
$mysqli->set_charset("utf8")
*With PDO_MySQL (as you connect)*
$pdo = new PDO(
'mysql:host=hostname;dbname=defaultDbName',
'username',
'password',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8")
);
The MySQL Database
We’re pretty much there now, you just need to make sure that MySQL knows to store the data in your tables as UTF-8. You can check their encoding by looking at the Collation value in the output of SHOW TABLE STATUS (in phpmyadmin this is shown in the list of tables).
If your tables are not already in UTF-8 (it’s likely they’re in latin1) then you’ll need to convert them by running the following command for each table:
ALTER TABLE myTable CHARACTER SET utf8 COLLATE utf8_general_ci;
One last thing to watch out for
With all of these steps complete now your application should be free of any character set problems.
There is one thing to watch out for, most of the PHP string functions are not unicode aware so for example if you run strlen() against a multi-byte character it’ll return the number of bytes in the input, not the number of characters. You can work round this by using the Multibyte String PHP extension though it’s not that common for these byte/character issues to cause problems.
Taken form here: http://webmonkeyuk.wordpress.com/2011/04/23/how-to-avoid-character-encoding-problems-in-php/
Try after setting the content type with header like this
header('Content-Type: text/html; charset=utf-8');
Try this function - >
$html = "Bla Bla Bla...";
$html = mb_convert_encoding($html, 'HTML-ENTITIES', "UTF-8");
for more - http://php.net/manual/en/function.mb-convert-encoding.php
I put together this method and called it in the file I'm working with, and that seemed to resolve the issue.
function setutf_8()
{
header('content-type: text/html; charset: utf-8');
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
mb_http_input('UTF-8');
mb_language('uni');
mb_regex_encoding('UTF-8');
ob_start('mb_output_handler');
}
Thank you for all your help! :)
I have come across some problems when inputting certain characters into my mysql database using php. What I am doing is submitting user inputted text to a database. I cannot figure out what I need to change to allow any kind of character to be put into the database and printed back out through php as it's suppose to.
My MySQL collation is: latin1_swedish_ci
Just before I send the text to the database from my form I use mysql_real_escape_string() on the data.
Example below
this text:
�People are just as happy as they make up their minds to be.�
� Abraham Lincoln
is suppose to look like this:
“People are just as happy as they make up their minds to be.”
― Abraham Lincoln
As mentioned by others, you need to convert to UTF8 from end to end if you want to support "special" characters. This means your web page, PHP, mysql connection and mysql table. The web page is fairly simple, just use the meta tag for UTF8. Ideally your headers would say UTF8 also.
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
Set your PHP to use UTF8. Things would probably work anyway, but it's a good measure to do this:
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
mb_http_input('UTF-8');
For mysql, you want to convert your table to UTF8, no need to export/import.
ALTER TABLE table_name CONVERT TO CHARACTER SET utf8
You can, and should, configure mysql to default utf8. But you can also run the query:
SET NAMES UTF8
as the first query after establishing a connection and that will "convert" your database connection to UTF8.
That should solve all your character display problems.
The likeliest cause of the problem is that the database connection is set to latin1 but you are feeding it text encoded in UTF-8. The simplest way to solve this is to convert your input into what the client expects:
$quote = iconv("UTF-8", "WINDOWS-1252//TRANSLIT", $quote);
(What MySQL calls latin1 is windows-1252 in the rest of the world.) Note that many characters, such as the quotation dash U+2015 that you use there, cannot be represented in this encoding and will be converted into something else. Ideally you should change the column encoding to utf8.
An alternative solution: set the database connection to utf8. It doesn't matter how the columns are encoded: MySQL internally converts text from the connection encoding into the storage encoding, you can keep the columns as latin1 if you want to. (If you do, the quotation dash U+2015 will be turned into a question mark ? because it's not in latin1)
How to set the connection encoding depends on what library you are using: if you use the deprecated MySQL library it's mysql_set_charset, if MySQLi it's mysqli_set_charset, if PDO add encoding=utf8 to the DSN.
If you do this you'll have set the page encoding to UTF-8 with the Content-Type header.
Otherwise you would be having the same problem with the browser: feeding it text encoded in UTF-8 when it's expecting something else:
header("Content-Type: text/html; charset=utf-8");
The solutions provided are helpful if starting from scratch. Putting all possible connections to UTF-8 is indeed the safest. UTF-8 is the most used charset on the net for a variety of reasons.
Some suggestions and a word of warning:
copy the tables you want to sanitize with a unique prefix (tmp_)
although your db-connection is forced to utf8, check you General Settings collation, change to utf8_bin if that was not done yet
you need to run this on the local server
the funny char error is mostly due to mixing LATIN1 with UTF-8 configurations. This solution is designed for this. It could work with other used char-sets that LATIN1 but I haven't checked this
check these tmp_tables extensively before copying back to the original
Builds the 2 array needed for the magic:
$chars = get_html_translation_table(HTML_ENTITIES, ENT_QUOTES, "UTF-8");
$LATIN1 = $UTF8 = array();
while (list($key,$val) = each ($chars)) {
$UTF8[] = $key;
$LATIN1[] = $val;
}
Now build up the routines you need: (tables->)rows->fields and at each field call
$row[$field] = mysql_real_escape_string(str_replace($LATIN1 , $UTF8 , $row[$field]));
$q[] = "$field = '{$row[$field]}'";
Finally build up and send the query:
mysql_query("UPDATE $table SET " . implode(" , " , $q) . " WHERE id = '{$row['id']}' LIMIT 1");
change the MySQL collation to utf8_unicode_ci or utf8_general_ci, including the table and the database.
You will need to set your database in utf-8 yes. There is many ways to do it. By changin the config file, via phpmyadmin or by calling php function (sorry memory blank) right before insert and update the mysql.
Unfortunately, i think you will have to re-enter any data you entered before.
One thing you also need to know, from personnal experience, make sure all table with relation have the same collation or you won'T be able to JOIN them.
as reference: http://dev.mysql.com/doc/refman/5.6/en/charset-syntax.html
Also, i can be a apache setting. We've experienced the same issue on 'free-hosting' server as well as on my brother's server. Once switched to another server, all the charater's became neat. Verfiy you apache setting, sorry but i can't bting more light on apache's config.
Get rid of everything you just need to follow these two points, every problem regarding special languages characters will be resolved.
1- You need to define the collation of your table to be utf8_general_ci.
2- define <meta http-equiv="content-type" content="text/html; charset=utf-8"> in the HTML after head tag.
2- You need to define the mysql_set_charset('utf8',$link_identifier); in the file where you made connection with the database and right after the selection of database like 'mysql_select_db' use this 'mysql_set_charset' this will allow you to add and retrieve data properly in what ever the language it is.
If your text has been encoded and decoded with the wrong encoding and so the mojibake is actually "solidified" into unicode characters, then the solutions mentioned so far won't work. I ended up having success with the ftfy Python package to automatically detect/fix mojibake:
https://github.com/LuminosoInsight/python-ftfy
https://pypi.org/project/ftfy/
https://ftfy.readthedocs.io/en/latest/
>>> import ftfy
>>> print(ftfy.fix_encoding("(ง'⌣')ง"))
(ง'⌣')ง
Hopefully this helps people who are in a similar situation.
I'm having encoding problems in my webpage, and it is driving me crazy. Let me try to explain
I have a meta tag defining utf8 as charset.
I'm including the scripts as utf8 too (<script type="text/javascript src="..." charset="utf8"></script>).
In .php files, I declare header('Content-Type: text/html; charset=utf8');
In my database (postgreSQL), I've made the query show lc_collate; and the return was en_US.UTF-8
I'm using AJAX
When I try to save the field value "name" as "áéíóú", I get the value "áéÃóú" in the record set (using phpPgAdmin to view results).
What am I doing wrong? There's a way to fix it without using decode/encode? Someone have a good reference about theses issues?
Thank you all!
Maybe the client encoding is not set correctly? PostgreSQL automatically converts between the character encoding on the client and the encoding in the database. For this to work it needs to know what encoding the client is using. Safest is to set this when you open your connection using:
SET CLIENT_ENCODING TO 'UTF8';
For details see the docs
You might be storing the data as ISO-8859-1?
Try enconding to base64 and decoding on the other end.
