When I submit a form (GET or POST), characters only in the iso-8859-2 charset (like ????) are not converted from quoted-printable to their 1-character-long representations, instead they left unchanged like õ etc.

I set the charset in the httpd.conf file, in the php.ini file, in the header of the html file and in the accept-charset attrib. of the form tag, but with no avail.

I tried it in NN, Opera and IE.

One more thing: sometimes it works correctly, but most of the time it doesn't. So strange enough!

Then some more info:

Here is an example:
http://www.parbanszep.hu/aa.php

And the file:
<html>
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-2">
</head>
<body>
<h1><?=htmlspecialchars($xx);?></h1>
<form method="post">
<input type="text" name="xx" value="<?=$xx?>">
<textarea name="yy"><?=htmlspecialchars($yy);?></textarea>
<input type="submit">
</form>
</body>
</html>

Now try to enter ???? into the two fields, they will become &#245; etc. instead of their one-char-form.

By default, htmlspecialchars() treats the input character set as iso-8859-1. If you want to specify it, you need to pass the appropriate charset name to the function via the third parameter. For more info, see http://www.php.net/htmlspecialchars.

And moreover, htmlspecialchars() doesn't support iso-8859-2.

Here's the list of supported charsets:

ISO-8859-1 (alias: ISO8859-1)
ISO-8859-15 (alias: ISO8859-15)
UTF-8
cp1252 (alias: Windows-1252, 1252)
BIG5 (alias: 950)
GB2312 (alias: 936)
BIG5-HKSCS
Shift_JIS (alias: SJIS, 932)
EUCJP (alias: EUC-JP)

I think this list should have been put on the manual in the first place. Let me marking this problem report as Documentation Problem.

Thanks for your report.
