Yep. I've found this problem recently while trying to write a script that would reparent (change the root of the folders with the files), check and let me fix my loads of /\.m3u8?/ files. Horrible mess. Plus you would not believe what does copying the folders from a unix filesystem do to names containing accentuated letters. And the names were in Spanish (latin1), I do not want to try to imagine what would happen if they were in Czech (latin2) :-(
Enoch was right!
Enjoy the last years of Rome.
