The letter "è" is encoded in CP-1252 as /0xE8/[1]. In UTF-16 it is
encoded by *two* bytes: 0x00 0xE8 (or vice versa, depending on the
endianess).
I have created a file "tèst" on a German Windows XP on NTFS, and started
a PHP shell:
>>> $fs = glob('t?st')
>>> $fs[0]
't\350st'
Apparently, the file name is *read* by PHP as if it was encoded in
CP-1252. Either the description on MSDN[2] is wrong, or PHP uses a
Windows API that converts the filename's encoding. I presume the
latter, being aware (but not (yet) convinced) that there might be
another reason for this behavior.
