gswin32c.exe now assumes that all input from stdin has been UTF8 encoded, and
similarly writes all output UTF8 encoded. Characters that come in with top bits
set will therefore confuse things.

Ideally we should process stdin so that we cope with unicode input, encoding as
we go, and stdout so we convert utf8 back to unicode. In the case of file
redirection, we want the files to come in exactly as they are though, so the
unicode->utf8 munging should only effect things when the input is a terminal.
