terminal: support entering non-ascii characters

Browse Source 
Unless the alt modifier is active and the MODE_ALT_SENDS_ESC mode is not
set, any value over 127 is converted to a UTF8 sequence.

Part of https://bugs.freedesktop.org/show_bug.cgi?id=53648 should be
fixed with this.

Part of https://bugs.freedesktop.org/show_bug.cgi?id=52419 is fixed, but
interestingly it depends on the activated keymap (i.e. it works with
dvorak, but not with ch).
