mysql_escape_string — Escapes a string for use in a mysql_query
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
Description
string mysql_escape_string
( string
$unescaped_string
)
This function will escape the unescaped_string,
so that it is safe to place it in a mysql_query().
This function is deprecated.
This function is identical to mysql_real_escape_string() except that mysql_real_escape_string() takes a connection handler and escapes the string according to the current character set. mysql_escape_string() does not take a connection argument and does not respect the current charset setting.
Warning
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
Parameters
-
unescaped_string -
The string that is to be escaped.

it seems the function changes the character encoding of the string.
I get utf-8 encoded string and my mysql database is set to utf-8 as well.
If i just write the data to the database it works perfectly fine, if i use this function, it changes the encoding and therefore stores the wrong characters.
Seems like a bug to me.
