I think it's worth including such functionality (especially as we
already depend on utf8-string in XMC). I often run Wikipedia & Google
searches on terms which include accents and other such UTFy things,
and it's a little tiresome fixing the search. Likely they are coming
pre-mangled by X, but if the spawn functions are also guilty then this
would at least be a step further.
That said, it's also worth asking where this should be done. Do we
leave XMonad core alone, and provide spawnU in XMC (and rewrite the
~53 XMC calls to call spawnU)?
