Removing invalid characters from a string

[HaMsTeYr]

I don't know if I'm not looking hard enough, but I couldn't find a topic on this, so I'm posting it here.

Essentially, in my nsis program I'm running some of the files have strange characters like " ®" or "©". They're problemful for me and I need them removed from the string itself.

So for example, $0 contains:

"Application Name Example® v1.0"

I need it to become:

"Application Name Example v1.0"

I know there are results about removing the more standard 'found on keyboard' invalid characters, but what about ones like these?

I've tried:

code:
${WordReplace} "$0" "®" "" "+" $0

But that doesn't seem to work.

Any workaround to this?
