如何删除这个特殊字符? [英] How to remove this special character?

问题描述

当我观察到以下内容时，我试图统一文件中的行:

word1 word2
word1 word2

我不明白为什么这些行没有合并，所以我在 vim 中打开文件并使用 :set list 查看是否有任何特殊字符，我发现了这个:

 word1  word2字 1 字 2

我不知道如何在 Python 中清理这个词.关于可能是什么字符以及如何清理它的任何建议?

解决方案

U+FEFF 是 字节顺序标记 字符，它应该只出现在文档的开头.在文档中，应将其视为零宽度非中断空间.如果这会导致问题，您可以像删除任何其他字符一样将其删除:

<预><代码>>>>s = u'word1 \ufeffword2'>>>s = s.replace(u'\ufeff', '')>>>秒u'word1 word2'

_{(在 Python 3.1 或 3.2 中，去掉字符串前面的 u)}

I was trying to unify the lines in my file when I observed the following:

word1 word2
word1 word2

I did not understand why these lines were not combined so I opened the file in vim and used :set list to see if there are any special characters and I found this:

 word1 <feff>word2
 word1 word2

I am not sure how to clean this word in Python. Any suggestions on what character might be and how this can be cleaned?

解决方案

U+FEFF is the Byte Order Mark character, which should only occur at the start of a document. In documents, it should be treated as a ZERO WIDTH NON-BREAKING SPACE. If this causes issues, you can remove it like any other character:

>>> s = u'word1 \ufeffword2'
>>> s = s.replace(u'\ufeff', '')
>>> s
u'word1 word2'

_{(In Python 3.1 or 3.2, drop the u in front of strings)}
