Whenever I try to declare a "Regular Expression" while including symbols like "+", "-", "*", the match is done based on how those operators work.
Now, when I try to use the regex API via combining those operators with backslash or \Q and \E I get the error message--
"...Illegal escape character".
I'm using TextPad at the moment, however the error is thrown by the compiler which makes me wonder if I need to upgrade or if there's a specific file to download to use regex API legally.
