Hebrew Directory Names

Hi I have wrote a files-based php system which not requires any kind of database to work, it is based upon files and directories. I'm using scandir() to fetch the file names of a directory, when the files and the directories are in English everything works like a charm, the problems starting when the files or the directories are in Hebrew. I tried several encodings for the directory names (including UTF8) but no luck so far. I always get is_file() === FALSE when the directory name is in Hebrew and the filename is in English. Any ideas?? The path which I'm checking with is_file() is: string(63) "/home/nitsanbn/public_html/iphoneia/walls/מחשבים/1346.jpg" (Due to the LTR encoding of this messege the filename is looking like it's in Hebrew, the directory is מחשבים and the filename is 1346.jpg) Thanks in Advance, Nitsan
