Hi,
I have some string and need to remove all non-ASCII characters with sed ot tr or awk:

echo "Here% is my st@^rin$g" | sed '???'

Checked s/[^[:ascii:]]//g or s/[^!-~\s]//g  - doesn't work

Thanks,

Did you mean you want to remove punctuation?

echo 'Here% is my st@^rin$g' | sed 's/[[:punct:]]//g'
