For example:sed 's/\u0091//g' file1Right now, I have to do hexdump to get hex number and put into sed as follows:$ echo -ne '\u9991' | hexdump -C00000000  e9 a6 91                                          |...|00000003And then:$ sed 's/\xe9\xa6\x91//g' file1
Is there an alternative to sed that supports unicode?
sed;unicode;hexdump
