It's a bug in the weird locale.getlocale() function which produces a locale
name which doesn't exist:
vstinner@WIN C:\vstinner\python\master>python
>>> import locale
>>> locale.setlocale(locale.LC_CTYPE, "tr_TR")
'tr_TR'
>>> locale.setlocale(locale.LC_CTYPE, None)
'tr_TR'
>>> locale.getlocale(locale.LC_CTYPE)
('tr_TR', 'ISO8859-9')
>>> locale.setlocale(locale.LC_CTYPE, ('tr_TR', 'ISO8859-9'))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\vstinner\python\master\lib\locale.py", line 610, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting
>>> locale.setlocale(locale.LC_CTYPE, 'tr_TR')
'tr_TR'
If you use setlocale(LC_CTYPE, None) to get the locale, it works as expected.
IMO the getlocale() function is dangerous and should be removed: see bpo-43557
"Deprecate getdefaultlocale(), getlocale() and normalize() functions".
