I disagree. We are talking about portable Haskell, not portable C.

The native Windows filename encoding (in WinNT) is UTF-16 (without
validation that surrogates are correctly paired). It provides API
which works with such filenames.

It also provides a compatibility layer on top of that, which tries
to translate filenames to some 8-bit encoding, but it should only be
used when porting C programs which can't be adapted to use Windows
filenames through their native type. Especially as Haskell already
uses Unicode - it's pointless to convert it to an 8-bit encoding and

I don't know what these 8-bit WinAPI functions do when they encounter
filenames unrepresentable in the current 8-bit encoding.
