I think we all know this, but this is not the point.

What does this mean?
If I use DELETE on a String type (that is an UTF-8 string)
does it now use UTF8Delete internally?
Does it delete bytes or code points?
Does LENGTH now give back the number of bytes or the
number of characters (when used on an UTF-8 String)?

Maybe, but without fully understanding the mechanism it is worse in the first place.
