I have a trouble displaying Cyrillic characters properly. Looked in forums, tried a few different thing and nothing works.
Site runs on PHP / MySQL.
MySQL tables charset is utf8, and collation is utf8_general_ci
Name entry in DB looks correct (in PhpmyAdmin):
Sasha Рукина
Output on page http://www.sodaq.com/: Sasha ??????
Inside PHP I use:
mb_internal_encoding("UTF-8");
mb_http_output("UTF-8");
And send HTTP header 'Content-type: text/html; charset=utf-8'
Still, shows '????' instead of normal characters.
Please help.
try to execute the following query before loading your data
SET NAMES 'utf8';
Have you also tried:
set character_set_connection=utf8;
You didn't mention the font you're using, but it's a big factor. Not all fonts contain all character sets.

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.

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! :)
In my database, I have some content like this
അവരുടെ മനസ്സുകളില്.
But, when i am trying to fetch the content using PHP and display it in broswer, it is showing only some question marks like ????????? ???????. ??????.
I tried to set the content type header like this
header('Content-Type: text/html; charset=utf-8');
But it doesnt work.
How can i solve this ? any help would be greatly appreciated.
It does not work because you got this broken during data fetch and you are setting display encoding - it's already too late. Simply ensure correct encoding during connection by using either using proper method like mysqli_set_charset() or do query SET NAMES UTF8 just after your connect to DB
Depending on the method you are using to connect to the DB, you should be specifying the charset.
With PDO, you can specify the charset in PDO::__construct(), such as: charset=UTF-8
Otherwise you have mysqli::set_charset() for MySQLi, or god forbid you're still using mysql_* functions there's mysql_set_charset()
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',$link_identifier); in the file where you made connection with the database and right after the selection of database like 'mysql_select_db' use this 'mysql_set_charset' this will allow you to add and retrieve data properly in what ever the language it is.
If your text has been encoded and decoded with the wrong encoding and so the mojibake is actually "solidified" into unicode characters, then the solutions mentioned so far won't work. I ended up having success with the ftfy Python package to automatically detect/fix mojibake:
https://github.com/LuminosoInsight/python-ftfy
https://pypi.org/project/ftfy/
https://ftfy.readthedocs.io/en/latest/
>>> import ftfy
>>> print(ftfy.fix_encoding("(ง'⌣')ง"))
(ง'⌣')ง
Hopefully this helps people who are in a similar situation.
In phpmyadmin I have stored a few russian values, using utf8_unicode_ci encoding. They are shown perfectly in phpmyadmin.
The problem appears when I get those values with php and I try to put them into options of a select, they are shown as "??????".
I've tried changing the encoding in the headers to iso-8859-1 instead of utf-8 but it doesn't work neither.
I've also tried with
mb_convert_encoding($str, 'UTF-8', 'auto');
but no change :(
Any other idea??
If you're using a MySQL DB/connection, use mysql_query("SET NAMES 'utf8'"); before your run your query, though a better alternative is mysql_set_charset().
Also ensure you have the entry:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
In the header section of your page.
If you're using PDO, change your connection to:
$PDO_connection = new PDO("mysql:host=".$db['host'].";dbname=".$db['name'],
$db['user'], $db['pword'],
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8")
I've tried changing the encoding in the headers to iso-8859-1 instead of utf-8
What for? what's the point in changing right encoding that support russian characters to wrong one that doesn't?
In order to achieve proper encoding on your page, you u have to do 2 things:
To tell the database what encoding you're expecting your data in. It should be done with mysql_set_charset('utf8') (or similar function of other library if you'r using one) where utf8 is the name of the encoding in mysql lingo.
to tell a browser what encoding your page in. it should be done with Content-type HTTP header, using header ('Content-type: text/html; charset=utf-8'); and nothing else.
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.
