如何搜索和替换不可打印的字符 [英] How to search and replace an unprintable character

问题描述

我有一个从 Word 导出的文件，它用奇怪的 unicode 字符替换了所有引号，这些字符在 vim 中没有正确显示.所以现在我想用引号替换这些字符，但我不知道如何在

I've a file that was exported from Word and it replaced all quotes with strange unicode characters which aren't correctly displayed in vim. So now I want those characters to be replaced with quotes, but I don't know how to enter this character in

:%s/???/'/g

字符看起来像这样:~U ~R.但当然我不能只用鼠标标记它们并粘贴到命令中.

The characters look like this: ~U ~R. But of course I can't just mark them with mouse and paste in the command.

推荐答案

您可以尝试设置编码类型，看看它是否修复了这些字符的可视化:

You can try setting the encoding type and see if it fixes the visalizations of those characters:

:set encoding=utf-8

然后就可以直接使用了.或者，您可以将光标放在不可打印的字符上并点击 ga，它将显示该字符的十进制/十六进制/八进制代码，然后您可以将其替换为:

then you can use them directly. Alternatively, you can place your cursor on the unprintable character and hit ga, it will show the decimal/hex/octal code of that character, then you can substitute it with:

:%s/\%xYY/substitute/g

其中 YY 是字符的十六进制代码，如果它是多字节的:

where YY is the hex code of the char, if it's multibyte:

:%s/\%uYYYY/substitute/g

请注意，您可以使用 \%xff 或 \%uabcd 进行搜索和匹配，但将是 无法替代.

Note that you can search and match with \%xff or \%uabcd but will be unable to substitute with it.
