Looking at the code of Path::Class::Unicode, it is broken at least on some non-Windows operating systems (well, actually on some filesystems). It seems to assume that all file systems will export their entities as UTF-8, which is a fairly broad assumption given VFAT and NFS, which only since v4 in 2009 makes claims on the encoding.
