My dream is that the compiler magic - when implemented in a way that 
supports auto-conversion for a fully dynamically encoded string type, 
additionally allows for arbitrary user-defined Strings type IDs (as well 
statically defined when creating the variable, when found in the 
encoding id field of a fully dynamically encoded variable). When seeing 
some of those, user-provided functions should be called instead of the 
(or by the) normal library call to allow for a user program implement 
it's own handling of propriety encoding schemes.

Obviously in many cases theses encoding schemes will be based on 
commonly used ones and the user functions will call library function on 
the way. Your "(tm)" example and "html entities" could nicely be handled 
in such a way without the fpc team needing to bother.
