词法错误:遇到:“" (0)，在:“"之后. [英] Lexical error: Encountered: "" (0), after : ""

问题描述

我需要开始处理外来字符，在这种情况下，我认为我很容易弄乱文件的编码.

I needed to start dealing with foreign characters, and in doing so, I think I royally screwed up a file's encoding.

我得到的错误是:

Lexical error at line 1, column 8.  Encountered: "" (0), after :  ""

文件的第一行是:

import xml.etree.cElementTree as ET

还要注意:当我将上面的行粘贴到textarea中问这个问题并提交时，每个字符之间都出现了一个未知字符(例如 我无法通过添加明确的编码定义来解决此问题:

Also of note: when I pasted the line above into the textarea to ask this question, and submitted, an unknown character appeared between every character (e I have been unable to fix this issue by adding an explicit coding definition:

# -*- coding: utf-8 -*-

我也无法将文件(使用Hg)还原到以前的版本，也无法将代码复制/粘贴到新文件中，也无法用复制/粘贴的代码替换损坏的文件.

I have also been unable to revert the file (using Hg) to a previous version, nor copy/paste code into a new file, or replace the broken file with copied/pasted code.

请帮助！

推荐答案

如果其中确实是零字符，则可能会发现您注入了一些UTF-16/UCS-2文本.特定的Unicode编码在每个ASCII字符之间都有一个零字节.

If it is indeed a zero character in there, you may find you've injected some UTF-16/UCS-2 text. That particular Unicode encoding would have a zero byte in between every ASCII character.

找出答案的最佳方法是使用od -xcb myfile.py之类的文件对文件进行十六进制转储.

The best way to find out is to do a hex dump of you file with something like od -xcb myfile.py.

如果是 情况，那么您需要使用能够看到这些字符的内容来编辑文件，并对其进行修复.

If that is the case, then you'll need to edit the file with something that's able to see those characters, and fix them up.

vi是我的第一选择(因为这是我的习惯)，但是我不想与Emacs illuminati展开任何圣战.在vi中，它们很可能会显示为^@字符.

vi would be my first choice (since that's what I'm used to) but I don't want to start any holy wars with the Emacs illuminati. In vi, they'll most likely show up as ^@ characters.
