I added this call originally, mimicking the C plug-ins. Yet in Python,
this function is deprecated since Python 3.8 and removed in 3.10.
Looking closer in the docs, it looks like Python's gettext module works
differently.
While all the *gettext() functions return strings in the locale's
encoding in C, unless overriden by bind_textdomain_codeset() (therefore
we need this call, in order to have locale-independent string encoding),
this is not the case in Python, whose gettext() call is already
locale-independent. The gettext.bind_textdomain_codeset() function only
applies to the specific l*gettext() functions which are deprecated too.
Fixes the warning:
