python,shell,locale,charset

windows下,python控制台,编码 为gbk

用户输入为gbk,python内部用unicode

zi = u'字'

gbk输入 -> unicode内部表示

>>> zi

u'\u5b57' 内部表示

>>> print zi

字 　　　　内部表示->gbk输出

把内部表示转换为另一种编码存储

输出时,系统认为仍是unicode表示,因此输出乱码

http://docs.python.org/2/library/locale.html

locale.getdefaultlocale([envvars])

Tries to determine the default locale settings and returns them as a tuple of the form (language code, encoding).

According to POSIX, a program which has not called setlocale(LC_ALL, '') runs using the portable 'C' locale. Callingsetlocale(LC_ALL, '') lets it use the default locale as defined by the LANG variable. Since we do not want to interfere with the current locale setting we thus emulate the behavior in the way described above.

To maintain compatibility with other platforms, not only the 'LANG', in that order.

Except for the code 'C', the language code corresponds to None if their values cannot be determined.

>>> locale.getdefaultlocale()

('zh_CN', 'cp936')

wiki cp936约等于gbk
