Python、Unicode 和 Windows 控制台 [英] Python, Unicode, and the Windows console

问题描述

当我尝试在 Windows 控制台中打印 Unicode 字符串时，出现错误.

When I try to print a Unicode string in a Windows console, I get an error .

UnicodeEncodeError: 'charmap' 编解码器无法编码字符 ....

我认为这是因为 Windows 控制台不接受仅 Unicode 字符.解决这个问题的最佳方法是什么?有什么办法可以让 Python 自动打印 ? 而不是在这种情况下失败?

I assume this is because the Windows console does not accept Unicode-only characters. What's the best way around this? Is there any way I can make Python automatically print a ? instead of failing in this situation?

我使用的是 Python 2.5.

这是一个详细说明问题和解决方案的页面(在页面中搜索文本Wrapping sys.stdout into an instance):

Here is a page that details the problem and a solution (search the page for the text Wrapping sys.stdout into an instance):

PrintFails - Python Wiki

这是该页面的代码摘录:

Here's a code excerpt from that page:

$ python -c 'import sys, codecs, locale; print sys.stdout.encoding; \
    sys.stdout = codecs.getwriter(locale.getpreferredencoding())(sys.stdout); \
    line = u"\u0411\n"; print type(line), len(line); \
    sys.stdout.write(line); print line'
  UTF-8
  <type 'unicode'> 2
