So, Object types is indicated only for compatibility?

With Lazarus on Linux, I did some simple tests with UTF strings.
I found that the length of an AnsiString(CP_UTF16) is given in terms
of bytes and not of Words. Is this like it should ?
I found that pchar(s8) with an UTF-8 string works as expected, giving a
pointer to the UTF-8 encoded byte

Yes. Afaik that is not a sane combination, but Delphi

Which tobject do you mean? Objpas.tobject (Delphi) or objects.tobject (TP) ?

Object instead Class?
They are basically similar to records with methods (which we now have
as well...) if you use them directly (this means: not as pointer types):
they are located on the stack and nested objects are part of the memory

Afaik stack based TP Objects are not initialized and thus not safe for
automated types. (I looked into upgrading TV with ansistring a few years
back)
This is no longer correct, stack based objects are initialized and finalized
if necessary.

That depends on how the default string type is defined. Discussions about
that is postponed.

It doesn't make sense if your ultimate object is to get FPC changed or
amended.
It does make sense if you want your problem analysed and want alternate
suggestions.
I am just watching the proceeding of FPC and doing some test when I have
some spare time to do this.
Of course I would like to help making FPC better and - if possible -
more sane than Delphi. But I do see the limits.
