bash - sed 难以替代的字符

Answer 1

I think that the sed command you are looking for is this:

sed 's/\xE2\x80\x94/-/g' thisfile

\xE2\x80\x94 is hex for what I assume is the offending character sequence. (FYI, it is the UTF-8 code for character 2014, a long dash of some kind). This is preferable to trying to throw special characters directly into a sed command.

If this does not work, use hexdump to find out exactly what the offending bytes are.

hexdump -C thisfile
