Ok, I found an answer by remembering something Patrick wrote about 
release 0.5.27. The solution is to use the function Keep()
--- it could use small comment IMHO. Perhaps something like this:

/*
// Keep() stores the string argument and returns an intermediary string 
// that will not be affected by other patterns. Just before finally
// printing a page - i.e. in PrintText() - the intermediary string is 
// restored, thereby preserving the original string argument from any 
// additional transformations.
*/
function Keep($text) {
  global $KeepToken,$KPV,$KPCount;
  $KPCount++; $KPV[$KPCount]=$text;
  return $KeepToken.$KPCount.$KeepToken;
}
