Remove "�" from a string 1

[NetworkGhost]

Anyone now of anyway to remove special chacters like these "�" out of a string? There are other special chacters I would like to maintain. Just want to get rid of these ones. I was using TCL regsub but couldnt get it to work. Would really like to get this resolved.

Thanks

This approach

 echo  "asdf�jklö" | sed 's/[^a-zA-Z0-9\t\n;+#_-]//g'
asdfïjklö

removes ¿½ but not ïö - maybe "a-z" is interpreted as :alpha:, and therefore including all lowercase letters?
Let's see:

 echo  "asdf�jklöJKLÖ" | sed 's/[^abcdefghijklmnopqrstuvwxyz0-9ABCDEFGHIJKLMNOPQRSTUVWXYZ\t\n;+#_-]//g'
asdfjkl

The special character section isn't complete, but you got the idea.

I usually use tr -d with the octal \XXX code if it is single characters.
pipe the string to od -c to see the values of the offenders.

Try this:

echo "GARBAGE" | sed -e 's/[^ -~]//g' | read new_var

The sed search string basically is "NOT printable character
