Ruby - Simple way to escape regex characters

I have an expression like this:

 s.gsub! /[\?\/\\]/, ''

In fact, the list of forbidden characters is longer than that. Some require escaping, some don't. Is there a way I could just put the characters in some literal structure (?/\) and say "remove all these from the string". I'm aware of Regexp.quote but not sure how to use it in this context.

You can interpolate a statement inside a Ruby regular expression, exactly like you do for strings.

/#{...}/

In your case

s.gsub! /[#{Regexp.escape('?/\')}]/, ''
