It certainly is.

It's supposed to. Note that I said "/if/ you are reading a
single byte", meaning that I was talking about the (not
uncommon) curcumstance where the underlying operating system
presents you with bytes each of which represents a single
character (ie not something like utf-8). Haskell is supposed
to deal with Unicode internally, but the I/O system's
treatment of it is not currently in a happy state, at least
partly because of what lies beneath.

All over the place. There's this monstrous notion of
"locale" that means that if you move your computer across
the border from Germany into Poland and change the system
settings appropriately, all character files change their
meanings. It stems from files being untyped, and as all good
Haskell programmers know, untyped is a Bad Thing.
