It seems that File Handling in PHP doesn't work with certain characters (e.g. €) encoded UTF-8 if the path is hardcoded and the php-file saved as UTF-8.
Is it possible to make it work with all (or most western characters)? Is there a library which makes it possible maybe? Because I couldn't find any.
For example a folder named äöü&()éèàâêûô@$+ç%&=
!£_;{[]}~´¢¬§°#@¦…€` in windows won't work with is_dir().
