UTF-8到unicode或latin-1（是的，我阅读了FAQ） [英] UTF-8 to unicode or latin-1 (and yes, I read the FAQ)
问题描述
嗨！
我正在努力将UTF-8字符串转换为latin-1。至于
我知道要走的路是将UTF-8字符串解码为unicode和
然后再将其编码回latin-1？
所以我试过了：
''K\xc3 \ xb6ni''。decode（''utf-8''）＃''K \ xc3 \ xb6ni''应该是''K？nig''，
包含一个德语''变音符号''
但是因为python失败了假设要解码的每个字符串都是ASCII？
如何将此字符串转换为latin-1？
如何编写函数？喜欢：
def encode_string（string，from_encoding，to_encoding）：
＃????
Best问候，
诺埃尔

这应该有用，它确实对我有用：
>> s =''K\xc3 \ xb6ni''。decode（''utf-8''）
s
u''K\xf6ni''
>> print s
K？ni
你做了什么，它是怎么失败的？

不，Python会假设在这种情况下字符串为utf-8编码：
>>''K\xc3 \ xb6ni''。decode（''utf-8''）。encode（''latin1''）
''K\xf6ni''
您的代码必须在某处失败其他。尝试发布实际失败的代码
和实际追溯。
''K\xc3 \ xb6ni''。decode（''utf-8''）＃''K\xc3 \ xb6ni''应该是''K？nig''，确切地说，
K？ni。
？h，是的。

首先，非常感谢您回答这么快。我为一个
项目提出了python，如果我失败将会非常尴尬
将UTF-8字符串转换为latin-1。
我意识到我的问题不是UTF-8的解码。如果我尝试打印unicode字符串，则会打印出异常
。
UnicodeEncodeError：''ascii''编解码器不能编码字符u ''\ xf6''在
位置1：序数不在范围内（128）
但这完全不是问题，因为我现在可以将我的UTF-8字符串
转为unicode！问题再次出现在我的
屏幕前面。傻我......

再次，谢谢你的回复！
祝你好运，

Hi!
I''m struggling with the conversion of a UTF-8 string to latin-1. As far
as I know the way to go is to decode the UTF-8 string to unicode and
then encode it back again to latin-1?
So I tried:
''K\xc3\xb6ni''.decode(''utf-8'') # ''K\xc3\xb6ni'' should be ''K?nig'',
contains a german ''umlaut''
but failed since python assumes every string to decode to be ASCII?
How can I convert this string to latin-1?
How would you write a function like:
def encode_string(string, from_encoding, to_encoding):
#????
Best regards,
Noel

>>s = ''K\xc3\xb6ni''.decode(''utf-8'')
s
u''K\xf6ni''
>>print s
K?ni
what did you do, and how did it fail?

>>''K\xc3\xb6ni''.decode(''utf-8'').encode(''latin1'')
''K\xf6ni''
Your code must have failed somewhere else. Try posting actual failing code
and actual traceback.
''K\xc3\xb6ni''.decode(''utf-8'') # ''K\xc3\xb6ni'' should be ''K?nig'',
"K?ni", to be precise.?h, yes.

what did you do, and how did it fail?First, thank you so much for answering so fast. I proposed python for a
project and it would be very embarrassing for me if I would fail
converting a UTF-8 string to latin-1.
I realized that my problem ist not the decode to UTF-8. The exception
is raised by print if I try to print the unicode string.
UnicodeEncodeError: ''ascii'' codec can''t encode character u''\xf6'' in
position 1: ordinal not in range(128)
But that is not a problem at all since I can now turn my UTF-8 strings
to unicode! Once again the problem was sitting right in front of my
screen. Silly me...
;o)
Again, thank you for your reply!

Noel
