<0xEF> character showing up in files. How to remove them?

Question

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 cha

Answer 1

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.
