regex question

I'm trying to replace all characters that are not letters numbers and
white spaces in a string. I'm getting the characters eliminated in this
case a comma but the white space is eliminated to. How do I get around
that?

string = 'john, tony'
newTerms = string.gsub(/\W/, "")

thanks

=> "john tony"

is one way...
