RegEx with strange behaviour: matching String with back reference to allow escaping and single and double quotes?

You can't use a backreference inside a character class 1 will be interpreted as octal 1 in this case (at least in some regex engines, I don't know if this is universally true).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
