No i didn't knew what encoding the filesystem used to store filenames into. I assumed 'iso-8859-7' because the filename's chars used were of greek chars.

I quoted many other things in my previous post that you said, and asked so to understand whats going on but you didn't answer me those so i still don't have a clear picture of what went wrong and why the values returned from the form ain't matching one of the values of array @display_files.

A stream of bytes representing character data can be read as if it were anything at all -- it's just a stream of bytes -- but it's only going to make sense if it is interpreted correctly, according to the intended character encoding.

What do you mean by "can be read as if it were anything at all" (sorry my english aint that good) and i missed your point.
