Yes, that's the same as I understood.

From what I understand from here:
http://www.gtk.org/api/2.6/glib/glib-IO-Channels.html#g-io-channel-set-encoding
then g_io is capable of doing recoding internally, since it says that
"The internal encoding is always UTF-8.".  I understand that the idea is
that a GTK application can do everything in UTF-8 internally and g_io
takes care of recoding when one needs to interact with the messy
external world.  Which is quite cool, actually :)

Yes, they would need to add the coding attribute, or gnome-speech would
try to recode their input into ISO-8859-1 (latin1), probably failing
while trying to recode sequences that cannot be encoded in latin1.

Luckily, it's very simple to add the coding attribute: see the attached
patch for Telugu (I followed the URL you gave to download the sources).

Thanks!

That would be just fantastic.


Ciao,
