Unbreak libxo's handling of characters not representable in current locale

The xo_format_string_direct function loops forever never advancing the
processed string pointer when it encounters a character that makes
mbrtowc fail. Make it emit '?' character instead, as it seems this is
what the code intent was, sans bugs.
