< 0xEF，为0xBB，为0xBF>字符显示在文件中。如何删除它们？ [英] <0xEF,0xBB,0xBF> character showing up in files. How to remove them?

问题描述

我正在压缩JavaScript文件，压缩器抱怨我的文件中有字符。

如何搜索这些字符并删除它们？

解决方案

  perl -pi〜-CSD -e'/ ^ \x { fffe} //'file1.js path / to / file2.js 
  

我会假设该工具将如果您的文件中有其他utf-8，则断开，否则，此解决方法可能会帮助您。 （未验证...）

修改：添加了 -CSD 每tchrist的评论。

I am doing compressing of JavaScript files and the compressor is complaining that my files have  character in them.

How can I search for these characters and remove them?

解决方案

perl -pi~ -CSD -e 's/^\x{fffe}//' file1.js path/to/file2.js

I would assume the tool will break if you have other utf-8 in your files, but if not, perhaps this workaround can help you. (Untested ...)

Edit: added the -CSD option, as per tchrist's comment.
