UnicodeEncodeError: 'ascii' 编解码器无法编码字符 u'xe4' [英] UnicodeEncodeError: 'ascii' codec can't encode character u'xe4'

问题描述

我永久收到以下错误:

UnicodeEncodeError: 'ascii' codec can't encode character u'xe4' in position 27: ordinal not in range(128)

我已经试过了

1. x.encode("ascii", "ignore")
2. x.encode("utf-8")
3. x.decode("utf-8")

然而，没有任何效果.

解决方案

你必须从源头上发现这个字符是哪种编码.

我猜这是 ISO-8859-1(欧洲语言)，在这种情况下是ä"，但您应该检查一下.它也可以是西里尔字母或希腊字母.

参见 http://en.wikipedia.org/wiki/ISO/IEC_8859-1 获取此编码中字符的完整列表.

使用此信息，您可以要求 Python 对其进行转换:

在 Python 2.7 中

<预><代码>>>>s = 'xe4'>>>t = s.decode('iso-8859-1')>>>打印 t一个>>>对于 c in t:... 打印 ord(c)...228>>>u = t.encode('utf-8')>>>打印你一个>>>对于以字节(u)为单位的 c:... 打印 ord(c)...195164

String t 在 Python 中以 ISO-8859-1 内部编码.字符串 u 在内部以 UTF-8 编码，该字符在 UTF-8 中占 2 个字节.另请注意，print 指令知道"如何显示这些不同的编码.

I permanently get the following error:

UnicodeEncodeError: 'ascii' codec can't encode character u'xe4' in position 27: ordinal not in range(128)

I already tried

1. x.encode("ascii", "ignore")
2. x.encode("utf-8")
3. x.decode("utf-8")

However, nothing works.

解决方案

You have to discover in which encoding is this character at the source.

I guess this is ISO-8859-1 (european languages), in which case it's "ä", but you should check. It could also be cyrillic or greek.

See http://en.wikipedia.org/wiki/ISO/IEC_8859-1 for a complete list of characters in this encoding.

Using this information, you can ask Python to convert it :

In Python 2.7

>>> s = 'xe4'
>>> t = s.decode('iso-8859-1')
>>> print t
ä
>>> for c in t:
...   print ord(c)
...
228
>>> u = t.encode('utf-8')
>>> print u
ä
>>> for c in bytes(u):
...   print ord(c)
...
195
164

String t is internally encoded in ISO-8859-1 in Python. String u is internally encoded in UTF-8, and that character takes 2 bytes in UTF-8. Notice also that the print instruction "knows" how to display these different encodings.
