Public bug reported:
If you install Ubuntu in English with Tel Aviv as the timezone location,
the installer figures out that the applicable locale is en_IL and adds
the line
LANG="en_IL"
to /etc/default/locale.
en_IL is a perfectly fine locale name; actually it's *the* correct name
of the English/Israel locale for UTF-8 according to SUPPORTED. However,
Python does not agree. Python seems to generally presuppose that locale
names include the codeset component, even if it accepts locale names
without codeset if they are included in the hard coded dictionary
locale_alias in /usr/lib/python3.5/locale.py. However, en_IL is a
relatively new locale, and not (yet) included in locale_alias:
gunnar@gunnar-ubuntu-current:~$ python3
Python 3.5.2+ (default, Sep 22 2016, 12:18:14)
[GCC 6.2.0 20160927] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale
>>> locale.setlocale(locale.LC_CTYPE, 'en_IL')
'en_IL'
>>> mylocale = locale.getlocale(locale.LC_CTYPE)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.5/locale.py", line 577, in getlocale
return _parse_localename(localename)
File "/usr/lib/python3.5/locale.py", line 486, in _parse_localename
raise ValueError('unknown locale: %s' % localename)
ValueError: unknown locale: en_IL
>>> quit()
I got to know about this issue via <http://askubuntu.com/q/854950>. Now,
the problem is not limited to en_IL. New locales in glibc tend to be
UTF-8 only locales without the codeset included in their names in
SUPPORTED. glibc and Python will probably never be in sync.
One way to deal with this issue is to always add '.UTF-8' to such locale
names. For instance, 'en_IL.UTF-8' is understood by both glibc and
Python.
Probably this should be fixed in localechooser. Basically I'd like to
see a code snippet along these lines:
if [ "$LOCALE" = "${LOCALE%.*}" ]; then
LOCALE=$( echo $LOCALE | sed -r 's/([^@]+)/\1.UTF-8/' )
fi
I haven't prepared a patch, since I don't know where exactly it should
be inserted without breaking anything else. (Don't know how to test it
either.) Still hoping that somebody finds it important enough to fix.
