New submission from Serhiy Storchaka:
The locale module uses locale alias table derived from X11 locale.alias file
for mapping bare locale names without encodings to locale names with encodings.
However sometimes glibc default encoding for a locale differs from that used in
X11 locale.alias.
Here is full differences table:

For example with the en_IN encoding:
>>> import locale, _locale
>>> _locale.setlocale(locale.LC_CTYPE)
'en_IN'
>>> locale.getlocale()
('en_IN', 'ISO8859-1')
>>> locale.nl_langinfo(locale.CODESET)
'UTF-8'
>>> locale.setlocale(locale.LC_CTYPE, locale.getlocale())
