问题描述
这是一个非ASCII字符的tmp.py:
如果__name__ ==__main__:
s ='ß'
打印
运行它我收到以下错误:
$ b
追溯(最近的最后一次呼叫):
文件.\tmp.py,第3行,在< module>
打印
文件C:\Python32\lib\encodings\cp866.py,第19行,编码
return codecs.charmap_encode(input,self。错误,encoding_map)[0]
UnicodeEncodeError:'charmap'编解码器无法在位置0中编码字符\xdf:字符映射到< undefined>
Python文档:
我的检查编码方式是使用Firefox(也许有人会建议一些比较明显的)。我在Firefox中打开tmp.py,如果我选择View-> Character Encoding-> Unicode(UTF-8),它看起来很好,就是这个问题上面的方式(wthß
符号) p>
如果我把:
# - * - encoding:utf-8 - * -
作为tmp.py中的第一个字符串,它不会更改任何内容 - 错误仍然存在。
有人可以帮我找出我做错了什么?
您的不支持该字符:
>>> '\xdf'.encode('cp866')
追溯(最近的最后一次调用):
文件< stdin>,第1行,< module>
文件/opt/local/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/encodings/cp866.py,第12行,编码
return codecs.charmap_encode(输入,错误,encoding_map)
UnicodeEncodeError:'charmap'编解码器无法在位置0中编码字符\xdf:字符映射到< undefined>
Python正在处理它,它的输出编码无法处理。
您可以尝试在Windows控制台中使用 chcp 65001
来切换代码页; chcp
是一个Windows命令行命令来更改代码页。
在OS X上使用(使用UTF-8 )可以处理它很好:
>>> print('\xdf')
ß
Here is a little tmp.py with a non ASCII character:
if __name__ == "__main__":
s = 'ß'
print(s)
Running it I get the following error:
Traceback (most recent call last):
File ".\tmp.py", line 3, in <module>
print(s)
File "C:\Python32\lib\encodings\cp866.py", line 19, in encode
return codecs.charmap_encode(input,self.errors,encoding_map)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\xdf' in position 0: character maps to <undefined>
The Python docs says:
My way of checking the encoding is to use Firefox (maybe someone would suggest something more obvious). I open tmp.py in Firefox and if I select View->Character Encoding->Unicode (UTF-8) it looks ok, that is the way it looks above in this question (wth ß symbol).
If I put:
# -*- encoding: utf-8 -*-
as the first string in tmp.py it does not change anything—the error persists.
Could someone help me to figure out what am I doing wrong?
The encoding your terminal is using doesn't support that character:
>>> '\xdf'.encode('cp866')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/local/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/encodings/cp866.py", line 12, in encode
return codecs.charmap_encode(input,errors,encoding_map)
UnicodeEncodeError: 'charmap' codec can't encode character '\xdf' in position 0: character maps to <undefined>
Python is handling it just fine, it's your output encoding that cannot handle it.
You can try using chcp 65001
in the Windows console to switch your codepage; chcp
is a windows command line command to change code pages.
Mine, on OS X (using UTF-8) can handle it just fine:
>>> print('\xdf')
ß
