[TYPO3-Solr] Custom sorting fields - how to ignore quotes etc?

Dear Ingo,

thanks for your quick look at it.

Yes, that's what I was thinking about as well.

We would set up something like

sortingTitle_stringS = TEXT
sortingTitle_stringS {
   field = myHeadlineField
   postUserFunc = user_funcs->convertStringForSorting
}

I was wondering if there is some kind of default solr filter / helper 
that could be triggered via typoscript conf instead of using an own 
userFunc?

Regards,
Jochen
