gnome-terminal, well basically every terminal that isn't konsole, is
utterly incapable of rendering anything with complex shaping
(devanagari/gurumukhi/whatever for instance), i'd go on a limb and say
that it's defficiency in the underlying terminal emulation (VteTerminal?),
so claiming to support internationalization is disingenuous.
