Yes, it is sufficient, and I tested the patched gnome-speech for quite a
while enjoying for the first time a good trip at a spoken OpenOffice,
and a nice read of lots of accented characters.

I must admit I was surprised myself.  Apparently the g_io infrastructure
has been designed smartly so that UTF-8 applications can talk with the
external world in its many incarnations.

True.  And if one day the italian festival voice will be changed to take
utf-8, then gnome-speech will need changing as well.

However, I have currently no idea how to query a festival voice for the
preferred encoding.  Maybe there's a super-simple lisp function for
that, and we can get rid of the compiled-in per-voice encoding list.
Or, otherwise, it can be not compiled in but read from a config file.

To me it makes a lot of sense to send out data in UTF-8 by default: I
think that it's the italian voice that is broken in this regard.


Ciao,

Enrico
