Include straight double quotation mark in grep Search class TextWrangl

How can I add the straight double quotation character to the search class?

I use this for TextWrangler:

replace “[\!\?,\.:;”“'˜]” using “” options {search mode:grep, starting at top:true}

I tried this, but it doesn’t work:

replace “[\!\?,\.:;”“'˜\”]" using “” options {search mode:grep, starting at top:true}

replace "[!?,.:;""'˜\"]" using "" options {search mode:grep, starting at top:true}

You don’t need to escape regex metacharacters inside a regex class. You only need to escape the double-quote character in the AppleScript string representing that class.

Thank you!
