The encoded name for ANSI codepage 1252 is "\x83oo.exe". Python 2's
default encoding is ASCII, so the decoded result is u'\ufffdoo.exe'.
Even if it should be the filesystem encoding ('mbcs'), the result is
u"ƒoo.exe". Neither equals u"ƒőő.exe".

Instead, shouldn't it encode LOOKFOR as "mbcs" with errors="replace"
before comparing it to proc.info['name']?
