使Emacs使用UTF-8与Python交互模式 [英] Make Emacs use UTF-8 with Python Interactive Mode

问题描述

当我从Mac OS'Terminal.app启动Python时，python将该编码识别为UTF-8：

When I start Python from Mac OS' Terminal.app, python recognises the encoding as UTF-8:

$ python3.0
Python 3.0.1 (r301:69556, May 18 2009, 16:44:01) 
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.stdout.encoding
'UTF-8'

这对python2是一样的。 5，

This works the same for python2.5.

但是在Emacs里面，编码是US-ASCII。

But inside Emacs, the encoding is US-ASCII.

Python 3.0.1 (r301:69556, May 18 2009, 16:44:01) 
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.stdout.encoding
'US-ASCII'

如何使Emacs与Python，以便sys.stdout知道使用UTF-8？

How do I make Emacs communicate with Python so that sys.stdout knows to use UTF-8?

编辑：由于我没有代表编辑接受的答案，这里正是为我在Aquaemacs 1.6，Mac OS 10.5.6上工作。

Since I don't have the rep to edit the accepted answer, here is precisely what worked for me on Aquaemacs 1.6, Mac OS 10.5.6.

在python-mode-hook中，我添加了

In the python-mode-hook, I added the line

(setenv "LANG" "en_GB.UTF-8")

显然，Mac OS需要UTF-8，而dfa则表示Ubuntu需要UTF8。

Apparently, Mac OS requires "UTF-8", while dfa says that Ubuntu requires "UTF8".

另外，我不得不通过执行Cx RET p设置输入/输出编码，然后键入utf-8两次。我应该知道如何永久地设置这个。

Additionally, I had to set the input/output encoding by doing C-x RET p and then typing "utf-8" twice. I should probably find out how to set this permanently.

感谢dfa和Jouni共同帮助我找到答案。

Thanks to dfa and Jouni for collectively helping me find the answer.

这是我最后的python-mode-hook：

Here is my final python-mode-hook:

(add-hook 'python-mode-hook
  (lambda ()
        (set (make-variable-buffer-local 'beginning-of-defun-function)
             'py-beginning-of-def-or-class)
        (define-key py-mode-map "\C-c\C-z" 'py-shell)
        (setq outline-regexp "def\\|class ")
        (setenv "LANG" "en_GB.UTF-8"))) ; <-- *this* line is new

推荐答案

您的环境变量：

$ LANG="en_US.UTF8" python -c "import sys; print sys.stdout.encoding"
UTF-8
$ LANG="en_US" python -c "import sys; print sys.stdout.encoding"  
ANSI_X3.4-1968

in your python hook, try:

< （setenvLANGen_US.UTF8）
