使用unicode.encode（'rot13'）时如何修复UnicodeEncodingError

Question

The version of my python is 2.7.

For some reason, I need to use rot13 to convert a paragraph with encoding 'utf-8'. But when I run commands as followed:

s = u'€'
res = unicode.encode('rot13')

I get the following error message:

UnicodeEncodeError: 'charmap' codec can't encode character u'\€' in position 0: character maps to <undefined> . How can I fix this error? I was trapped in this error for long time, and can't fix it by the method on Google.

Answer 1

The rot13 codec can't do this in Python 2. It's hardcoded to use charmap. Switch to Python 3 or just write your own rot13.
