[PATCH 2/3] fhandler_pty_slave::setup_locale: fall back to UTF-8, not ASCII

[Johannes Schindelin]

When we fail to determine the Console output code page to use in the
Pseudo Console, we used to fall back to ASCII.

However, a much better fall-back code page is UTF-8 because that's what
Cygwin defaults to, internally, when no encoding was specified.

Besides, `/etc/profile.d/lang.sh` essentially sets `LANG=$(locale -uU)`
(where the `-U` says that `.UTF-8` should be appended). Meaning: we
_really_ want to use the UTF-8 code page.
