Every Delphi/FPC type has a bunch of operators. Strings support :=, =, <>, >=, <= and [] for read and write.
When you propose a new string type "dynamicstring" you have to define these operators. Otherwise your proposal is not a string, but just a magic unicorn.

There is no QWord codepage. That would be confusing.
