what is it for?

I think for those two cases, it is better to use dgettext directly.

When click a last language name on the language list, the position of the
scrollbar is bottom and the position needs to be moved to top on the engine
list.

OK, I added two new APIs gettext_engine_longname() and
gettext_engine_description().

what about if some engines share a same textdomain? Do you think if it is
necessary to track which textdomain has been initialized?

ui/gtk2/i18n.py:60: gettext.bind_textdomain_codeset(textdomain, 'UTF-8')
those code is similar to def init():

How about has a function init_textdomain(domainname)?

I think calling bindtextdomain() many times is not a big problem.
