fix: pass through escape sequences that result in aare special chars

Browse Source 
escape sequences that result in special character that will be interpreted
by later processing need to be passed through as well.

Eg. previously \\ was fixed to be passed through, but other chars
get interpretted as well.

*?[]{}
and ^, in character classes
