unicode - python 3.0，如何使print()输出unicode？

Question

我正在WinXP 5.1.2600中工作，编写了一个涉及中文拼音的Python应用程序，这使我陷入了无休止的Unicode问题。切换到Python 3.0已解决了许多问题。但是出于某些奇怪的原因，用于控制台输出的print（）函数不支持Unicode。这是一个小程序。

print('sys.stdout encoding is "' + sys.stdout.encoding + '"')
str1 = 'lüelā'
print(str1)

输出为（将尖括号更改为方括号以提高可读性）：

    sys.stdout encoding is "cp1252"    Traceback (most recent call last):      File "TestPrintEncoding.py", line 22, in [module]        print(str1)      File "C:\Python30\lib\io.py", line 1491, in write        b = encoder.encode(s)      File "C:\Python30\lib\encodings\cp1252.py", line 19, in encode        return codecs.charmap_encode(input,self.errors,encoding_table)[0]    UnicodeEncodeError: 'charmap' codec can't encode character '\u0101'     in position 4: character maps to [undefined]

Note that ü = \xfc = 252 gives no problem since it's upper ASCII. But ā = \u0101 is beyond 8-bits.

Anyone have an idea how to change the encoding of sys.stdout to 'utf-8'? Bear in mind that Python 3.0 no longer uses the codecs module, if I understand the documentation right.

Apologies, I gave you the program without the preamble. Before the 3 lines given, it starts like this:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys

不幸的是，“ coding：”行指定的编码是源代码的编码，而不是控制台输出的编码。但是谢谢您的想法！

Windows命令提示符（cmd.exe）无法显示您正在使用的Unicode字符，即使Python在内部以正确的方式对其进行了处理。您需要使用IDLE，Cygwin或其他可以正确显示Unicode的程序。
