Hello,

The htmlspecialchars() function should only convert SPECIAL chars such as '&' '"' ''' '<' '>'. (at least this is what the documentation says)

But this function also seems to convert foriegn language (non-english) chars too which is what htmlentities() basically does.

I have tested this on Russian and Hebrew!

Could you please supply a simple string with which the problem occures.

hmm after checking some more research i noticed that this happens only when the browser encoding != language you are writing.

So if you write in hebrew when the browser is set to encode Western European you will get something similar to this: "&#1506;&#1489;&#1512;&#1497;&#1514;" although i did solve all these problems by calling html_entities_decode() but still.. why should htmlspecialchars() encode anything but the SPECIAL chars, and not language chars..

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

Works fine here, the error you are seeing sounds like a result of COPY/PASTE operation from another Win32 application. Win32 has a nasty tendency to automatically encode special characters into their HTML enteties.
The example below should demonstrate that htmlspecialchars()  works correctly.
<?php
var_dump(htmlspecialchars("????"));
?>

Hi
Yes, I also recognized this problem with the hungarian chars!
I hope that I'll find the solutions around here...
