Where could I find the TAnsiString implementation that was once posted on Embarcadero Forums? I am trying to learn how to implement COW and reference counting.

    From different types, the assignment is handled with the implicit operator. From same type, it is a record copy, just a few bytes. The COW handles the rest, so there are no memory clashes.

    The real use of this library is not included here. A large library for communication I/O written in TP, where the different protocols are using either ansi characters or bytes (as short strings), is still used to a large extent in Delphi and TP. To make the library compatible with the Unicode Delphi2009+ and the changed AnsiString, it was needed to base the code on a type similar to TAnsiString.

    Leif Uneus Could this be adopted for UTF-8/16 aswell?

    Well, it is possible to adopt to use for UTF-8. I think Rudy Velthuis made that transition, but I'm not sure if he ever published the code. If that is done, it would be possible to exchange data fully with UTF16.
