Martin,

Let's go step by step!

USER do input 'm?ller's (data)'
Yes?

You need escape this USER INPUT only
And you get 

    'm\?ller's \(data\)'
        

Aha, I see problem...

Hmm, then really, it is USER must give you input

    
    'm?ller's \(data\)'


I.e. He self must specify that in this pattern symbols ()
Must be used as CHARS.

Is this answer ?
