* If I use hPutStr on a string, is it guaranteed that the number of 8-bit bytes written equals (length stringWritten)?

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.

Haskell doesn't specify an encoding. GHC and Hugs both assume ISO-8859-1. The only difference between binary and text modes is that text mode converts between the platform's EOL conventions (i.e. LF on Unix, CRLF on Windows) and LF. -- Glynn Clements
