But there's no guarantee that char is exactly 8 bits wide, is there? So 
it's appropriate to have separate types, CChar/CSChar/CUChar and 
Word8/Int8.

I submit that interfaces to network handles should all use Word8, because 
the standards all speak unambiguously of "octets". For files it's 
debatable perhaps, but I strongly lean towards Word8 for any "binary" 
(i.e. direct) file access. CChar/CSChar/CUChar are for FFI to C and C++.
