问题：u’\ ufeff’在Python字符串中

我收到以下错误消息：

UnicodeEncodeError: 'ascii' codec can't encode character u'\ufeff' in position 155: ordinal not in range(128)

不知道是什么u'\ufeff'，在我进行网页抓取时会显示出来。我该如何纠正这种情况？该.replace()字符串的方法不能进行这项工作。

I get an error with the following patter:

UnicodeEncodeError: 'ascii' codec can't encode character u'\ufeff' in position 155: ordinal not in range(128)

Not sure what u'\ufeff' is, it shows up when I’m web scraping. How can I remedy the situation? The .replace() string method doesn’t work on it.

Unicode字符U+FEFF是字节顺序标记或BOM，用于区分大尾数UTF-16编码之间的区别。如果您使用正确的编解码器解码网页，Python会为您删除它。例子：

#!python2
#coding: utf8
u = u'ABC'
e8 = u.encode('utf-8')        # encode without BOM
e8s = u.encode('utf-8-sig')   # encode with BOM
e16 = u.encode('utf-16')      # encode with BOM
e16le = u.encode('utf-16le')  # encode without BOM
e16be = u.encode('utf-16be')  # encode without BOM
print 'utf-8     %r' % e8
print 'utf-8-sig %r' % e8s
print 'utf-16    %r' % e16
print 'utf-16le  %r' % e16le
print 'utf-16be  %r' % e16be
print
print 'utf-8  w/ BOM decoded with utf-8     %r' % e8s.decode('utf-8')
print 'utf-8  w/ BOM decoded with utf-8-sig %r' % e8s.decode('utf-8-sig')
print 'utf-16 w/ BOM decoded with utf-16    %r' % e16.decode('utf-16')
print 'utf-16 w/ BOM decoded with utf-16le  %r' % e16.decode('utf-16le')

请注意，这EF BB BF是UTF-8编码的BOM。UTF-8不需要它，而仅用作签名（通常在Windows上）。

输出：

utf-8     'ABC'
utf-8-sig '\xef\xbb\xbfABC'
utf-16    '\xff\xfeA\x00B\x00C\x00'    # Adds BOM and encodes using native processor endian-ness.
utf-16le  'A\x00B\x00C\x00'
utf-16be  '\x00A\x00B\x00C'

utf-8  w/ BOM decoded with utf-8     u'\ufeffABC'    # doesn't remove BOM if present.
utf-8  w/ BOM decoded with utf-8-sig u'ABC'          # removes BOM if present.
utf-16 w/ BOM decoded with utf-16    u'ABC'          # *requires* BOM to be present.
utf-16 w/ BOM decoded with utf-16le  u'\ufeffABC'    # doesn't remove BOM if present.

请注意，utf-16编解码器要求存在BOM表，否则Python将不知道数据是大端还是小端。

The Unicode character U+FEFF is the byte order mark, or BOM, and is used to tell the difference between big- and little-endian UTF-16 encoding. If you decode the web page using the right codec, Python will remove it for you. Examples:

#!python2
#coding: utf8
u = u'ABC'
e8 = u.encode('utf-8')        # encode without BOM
e8s = u.encode('utf-8-sig')   # encode with BOM
e16 = u.encode('utf-16')      # encode with BOM
e16le = u.encode('utf-16le')  # encode without BOM
e16be = u.encode('utf-16be')  # encode without BOM
print 'utf-8     %r' % e8
print 'utf-8-sig %r' % e8s
print 'utf-16    %r' % e16
print 'utf-16le  %r' % e16le
print 'utf-16be  %r' % e16be
print
print 'utf-8  w/ BOM decoded with utf-8     %r' % e8s.decode('utf-8')
print 'utf-8  w/ BOM decoded with utf-8-sig %r' % e8s.decode('utf-8-sig')
print 'utf-16 w/ BOM decoded with utf-16    %r' % e16.decode('utf-16')
print 'utf-16 w/ BOM decoded with utf-16le  %r' % e16.decode('utf-16le')

Note that EF BB BF is a UTF-8-encoded BOM. It is not required for UTF-8, but serves only as a signature (usually on Windows).

Output:

utf-8     'ABC'
utf-8-sig '\xef\xbb\xbfABC'
utf-16    '\xff\xfeA\x00B\x00C\x00'    # Adds BOM and encodes using native processor endian-ness.
utf-16le  'A\x00B\x00C\x00'
utf-16be  '\x00A\x00B\x00C'

utf-8  w/ BOM decoded with utf-8     u'\ufeffABC'    # doesn't remove BOM if present.
utf-8  w/ BOM decoded with utf-8-sig u'ABC'          # removes BOM if present.
utf-16 w/ BOM decoded with utf-16    u'ABC'          # *requires* BOM to be present.
utf-16 w/ BOM decoded with utf-16le  u'\ufeffABC'    # doesn't remove BOM if present.

Note that the utf-16 codec requires BOM to be present, or Python won’t know if the data is big- or little-endian.

我在Python 3上遇到了这个问题，并找到了这个问题（以及解决方案）。打开文件时，Python 3支持encoding关键字来自动处理编码。

没有它，物料清单将包含在读取结果中：

>>> f = open('file', mode='r')
>>> f.read()
'\ufefftest'

给出正确的编码，结果中将省略BOM：

>>> f = open('file', mode='r', encoding='utf-8-sig')
>>> f.read()
'test'

只是我的2美分。

I ran into this on Python 3 and found this question (and solution). When opening a file, Python 3 supports the encoding keyword to automatically handle the encoding.

Without it, the BOM is included in the read result:

>>> f = open('file', mode='r')
>>> f.read()
'\ufefftest'

Giving the correct encoding, the BOM is omitted in the result:

>>> f = open('file', mode='r', encoding='utf-8-sig')
>>> f.read()
'test'

Just my 2 cents.

该字符是BOM或“字节顺序标记”。它通常作为文件的前几个字节接收，告诉您如何解释其余数据的编码。您只需删除字符即可继续。尽管由于错误提示您正在尝试转换为“ ascii”，但您可能应该为尝试执行的操作选择其他编码。

点击查看英文原文

That character is the BOM or “Byte Order Mark”. It is usually received as the first few bytes of a file, telling you how to interpret the encoding of the rest of the data. You can simply remove the character to continue. Although, since the error says you were trying to convert to ‘ascii’, you should probably pick another encoding for whatever you were trying to do.

您要抓取的内容是用unicode编码的，而不是ascii文本，并且您得到的字符不会转换为ascii。正确的“翻译”取决于原始网页的想法。 Python的unicode页面提供了其工作原理的背景信息。

您是要打印结果还是将其粘贴到文件中？该错误表明它正在写入导致问题的数据，而不是读取它。这个问题是寻找修补程序的好地方。

The content you’re scraping is encoded in unicode rather than ascii text, and you’re getting a character that doesn’t convert to ascii. The right ‘translation’ depends on what the original web page thought it was. Python’s unicode page gives the background on how it works.

Are you trying to print the result or stick it in a file? The error suggests it’s writing the data that’s causing the problem, not reading it. This question is a good place to look for the fixes.

这是基于Mark Tolonen的答案。该字符串包含单词“ test”的不同语言，用“ |”分隔，因此您可以看到其中的区别。

e8 = u.encode('utf-8')        # encode without BOM
e8s = u.encode('utf-8-sig')   # encode with BOM
e16 = u.encode('utf-16')      # encode with BOM
e16le = u.encode('utf-16le')  # encode without BOM
e16be = u.encode('utf-16be')  # encode without BOM
print('utf-8     %r' % e8)
print('utf-8-sig %r' % e8s)
print('utf-16    %r' % e16)
print('utf-16le  %r' % e16le)
print('utf-16be  %r' % e16be)
print()
print('utf-8  w/ BOM decoded with utf-8     %r' % e8s.decode('utf-8'))

It’s worth to know that only both utf-8-sig and utf-16 get back the original string after both encode and decode.

当您将Python代码保存为UTF-8或UTF-16编码时，基本上会出现此问题，因为python会在代码的开头自动添加一些特殊字符（文本编辑器未显示）以标识编码格式。但是，当您尝试执行代码时，它在第1行中给您带来语法错误，即代码开始，因为python编译器理解ASCII编码。当您使用read（）函数查看文件的代码时，您可以在返回的代码‘\ ufeff’。解决此问题的最简单方法就是将编码改回ASCII编码的开头看到（为此，您可以将代码复制到记事本中并保存它，记住！选择ASCII编码…希望这会有所帮助。

This problem arise basically when you save your python code in a UTF-8 or UTF-16 encoding because python add some special character at the beginning of the code automatically (which is not shown by the text editors) to identify the encoding format. But, when you try to execute the code it gives you the syntax error in line 1 i.e, start of code because python compiler understands ASCII encoding. when you view the code of file using read() function you can see at the begin of the returned code ‘\ufeff’ is shown. The one simplest solution to this problem is just by changing the encoding back to ASCII encoding(for this you can copy your code to a notepad and save it Remember! choose the ASCII encoding… Hope this will help.
