如何从 python 脚本中获取终端的编码？

Question

Let's say you want to start a python script with some parameters like

python myscript some arguments

I understand, that the strings sys.argv[1] and sys.argv[2] will have the encoding specified in the terminal. Is there a way to get this information from within the python script?

My goal is something like this:

terminal_enocding = some_way.to.GET_TERMINAL_ENCODING
some = `sys.argv[1]`.decode(terminal_encoding)
arguments = `sys.argv[2]`.decode(terminal_encoding)

Answer 1

sys.stdout.encoding will give you the encoding of standard output. sys.stdin.encoding will give you the encdoing for standard input.

Answer 2

You can call locale.getdefaultlocale() and use the second part of the tuple.

See more here (Fedora wiki entry explaining the why's and how's of the default encoding in Python)

Answer 3

The function locale.getpreferredencoding() also seems to do the job.

It returns the Python encoding string which you can directly use like this:

>>> import locale
>>> s = b'123\n'
>>> enc = locale.getpreferredencoding()
>>> s.decode(enc)
'123\n'
