Python编码/解码问题 [英] Python encoding/decoding problems

问题描述

如何将这样的字符串解码为正常编码。

How do I decode strings such as this one "weren\xe2\x80\x99t" back to the normal encoding.

所以这个字实际上是不是而不是aren\xe2\x80\x99t？
例如：

So this word is actually weren't and not "weren\xe2\x80\x99t"? For example:

print "\xe2\x80\x9cThings"
string = "\xe2\x80\x9cThings"
print string.decode('utf-8')
print string.encode('ascii', 'ignore')

“Things
"Things
Things

但我其实想要得到

或：

print "weren\xe2\x80\x99t"
string = "weren\xe2\x80\x99t"
print string.decode('utf-8')
print string.encode('ascii', 'ignore')

weren’t
weren’t
werent

但我实际上想要得到的不是。

But I actually want to get weren't.

我该怎么办？

推荐答案

我映射了最常见的奇怪的字符，所以这是基于Oliver W.答案的完整答案。

I mapped the most common strange chars so this is pretty much complete answer based on the Oliver W. answer.

这个功能绝非理想，但它是最好的起点与
有更多的字符定义：

This function is by no means ideal,but it is the best place to start with. There are more chars definitions:
