Usage of deprecated gettext.bind_textdomain_codeset

[Arfrever]

When Python warnings are enabled:

$ export PYTHONWARNINGS="d"
$ ibus-setup
/usr/share/ibus/setup/i18n.py:45: DeprecationWarning: bind_textdomain_codeset() is deprecated
  gettext.bind_textdomain_codeset(domainname, 'UTF-8')

https://docs.python.org/3.9/library/gettext.html#gettext.bind_textdomain_codeset says about gettext.bind_textdomain_codeset:

Bind the domain to codeset, changing the encoding of byte strings returned by the lgettext(), ldgettext(), lngettext() and ldngettext() functions.
...
Deprecated since version 3.8, will be removed in version 3.10.

IBus does not use any of gettext.lgettext, gettext.ldgettext, gettext.lngettext, gettext.ldngettext, which are also deprecated and scheduled for deletion:
https://docs.python.org/3.9/library/gettext.html#gettext.lgettext
