You've presumably got mintty set to UTF-8, hence mintty's output
conversion turned ls's ISO-8859-1 "=C3=85=C2=A4" (i.e. "\xC3\xA4") into "=
=C3=A4".

Both. For the latter, try it in the default Cygwin console, without
any locale variables set.

Thanks. Unfortunately the "C" locale is rather important though,
because that's what people will be using unless they go to the effort
of finding out how to set a different locale.
