Yes, if the handle is opened in binary mode. No if not.
Thank you for the informative response.
If a file is opened in text mode, what encoding does Haskell grok on input? And what encoding does it generate on output? I'm assuming it's UTF-8 on output, but I don't know for sure.
The ghc standard libraries only work with latin1, however, there are quite a few libraries out there for reading/writing text in the current locale (or a set format like UTF-8) so ghcs limitations are not too bad in practice if you need unicode. Some are even drop-in replacements for the standard prelude IO functions. It should also be said that these are limitations of the current haskell tools and not the language itself, the language specifies unicode and leaves the details of IO up to implementations.
