UnicodeDecodeError:"ascii"编解码器无法解码位置1的字节0xef [英] UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 1

问题描述

我在尝试将字符串编码为UTF-8时遇到一些问题.我已经尝试了很多事情，包括使用string.encode('utf-8')和unicode(string)，但是出现错误:

I'm having a few issues trying to encode a string to UTF-8. I've tried numerous things, including using string.encode('utf-8') and unicode(string), but I get the error:

UnicodeDecodeError:'ascii'编解码器无法解码位置1的字节0xef:序数不在范围内(128)

UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 1: ordinal not in range(128)

这是我的字符串:

我不知道出了什么问题，知道吗?

I don't see what's going wrong, any idea?

问题是按原样打印字符串不能正确显示.另外，当我尝试将其转换时出现此错误:

The problem is that printing the string as it is does not show properly. Also, this error when I try to convert it:

>>> print s1
Traceback (most recent call last):

UnicodeEncodeError: 'ascii' codec can't encode characters in position 1-5: ordinal not in range(128)

推荐答案

这与未将终端的编码设置为UTF-8有关.这是我的终端机

This is to do with the encoding of your terminal not being set to UTF-8. Here is my terminal

$ echo $LANG
en_GB.UTF-8
$ python
Python 2.7.3 (default, Apr 20 2012, 22:39:59) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> s = '(\xef\xbd\xa1\xef\xbd\xa5\xcf\x89\xef\xbd\xa5\xef\xbd\xa1)\xef\xbe\x89'
>>> s1 = s.decode('utf-8')
>>> print s1
(｡･ω･｡)ﾉ
>>> 

在我的终端上，该示例适用于上面的示例，但是如果我放弃了LANG设置，那么它将无法正常工作

On my terminal the example works with the above, but if I get rid of the LANG setting then it won't work

$ unset LANG
$ python
