UnicodeDecodeError：'ascii'编解码器无法解码 [英] UnicodeDecodeError: 'ascii' codec can't decode

问题描述

我正在用file.readline（）在Python中读取包含罗马尼亚语的文件。
由于编码，我遇到许多字符的问题。

I'm reading a file that contains Romanian words in Python with file.readline(). I've got problem with many characters because of encoding.

示例：

>>> a = "aberație"  #type 'str'
>>> a -> 'abera\xc8\x9bie'
>>> print sys.stdin.encoding
UTF-8

我已经尝试了utf-8，cp500等，但它不起作用。

I've tried encode() with utf-8, cp500 etc, but it doesn't work.

我找不到哪个是正确的字符编码我必须使用？

I can't find which is the right Character encoding I have to use ?

提前感谢。

编辑：目的是将文件中的单词存储在词典中，并在打印时将其打印到

The aim is to store the word from file in a dictionnary, and when printing it, to obtain aberație and not 'abera\xc8\x9bie'

推荐答案

你想做什么？

这是一组字节：

BYTES = 'abera\xc8\x9bie'

这是一组代表一个 utf-8 字符串aberaţie的编码。您解码以获取您的unicode字符串的字节：

It's a set of bytes which represents a utf-8 encoding of the string "aberație". You decode the bytes to get your unicode string:

>>> BYTES 
'abera\xc8\x9bie'
>>> print BYTES 
aberație
>>> abberation = BYTES.decode('utf-8')
>>> abberation 
u'abera\u021bie'
>>> print abberation 
aberație

如果要将unicode字符串存储到文件中，那么你必须将编码为您选择的特定字节格式：

If you want to store the unicode string to a file, then you have to encode it to a particular byte format of your choosing:

>>> abberation.encode('utf-8')
'abera\xc8\x9bie'
>>> abberation.encode('utf-16')
'\xff\xfea\x00b\x00e\x00r\x00a\x00\x1b\x02i\x00e\x00'
