Erronous "unsupporte d locale setting" ?

[robert]

Why can the default locale not be set by its true name? but only by '' ? :
PythonWin 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win32.

>>import locale
locale.getloc ale()

(None, None)

>>locale.setloc ale(locale.LC_A LL,"de_DE")

Traceback (most recent call last):
File "<interacti ve input>", line 1, in <module>
File "C:\Python25\li b\locale.py", line 476, in setlocale
return _setlocale(cate gory, locale)
Error: unsupported locale setting

>>locale.getdef aultlocale()

('de_DE', 'cp1252')

>>locale.setloc ale(locale.LC_A LL,locale.getde faultlocale())

'C'

>>locale.setloc ale(locale.LC_A LL,'')

'German_Germany .1252'

>>locale.getloc ale()

('de_DE', 'cp1252')

Probably it is just not implemented. But since locale names are system
specific (For example windows accepts 'ch' as Chinese in Taiwan, where
as IANA <http://www.iana.org/assignments/language-subtag-registry>
considers it Chamorro) setlocale should probably grow an additional
keyword parameter: setlocale(LC_AL L, iana='de-DE')

that'd be another fat database to blow up the python core(s).

I just wonder why locale.setlocal e(locale.LC_ALL ,"de_DE") doesn't accept the name, which

>>locale.getloc ale() / getdefaultlocal e()

('de_DE', 'cp1252')
already deliver ?

but only this works

>>locale.setloc ale(locale.LC_A LL,'German_Germ any.1252')

'German_Germany .1252'
But 'German_Germany .1252' you cannot get/guess from any locale.getxxxx function I think ...

It is documented that those functions return cross platform RFC 1766
language code. This code sometimes won't be compatible with OS specific
locale name. Cross platform code can useful if you want to create your
own locale database for example cross platform language packs.

Right now we have:

setlocale(categ ory) -- get(it's not a typo) OS locale name
getlocale(categ ory) -- get cross platform locale name
setlocale(categ ory,'') -- enable default locale, return OS locale name
getdefaultlocal e() -- get cross platform locale name

I agree it's very confusing API, especially setlocale acting like
getter, but that's what we have. Improvement is welcome.
