If that is "unthinkable" then define new contructors
TJSONParser.Create2(...,AUseUTF8 : Boolean = True) or Create2(...,AUseUTF8 :
Boolean = True) and mark the Create(...) as deprecated. Or deprecate
TJSONParser and make it a descendant of TJSONParser2 that has
Create(...,AUseUTF8 : Boolean = True) constructors.
