[Lazarus] TCDListbox implemented?

[Alexey via Lazarus]

I see not implemented, CustomDrawn demo don't show it. ...Why you cannot 
take ATListbox and make CDListbox on its base?

Neither was I - now I know it's not something that can be fixed on LCL/FPC side,
so that's that. Guess there's a reason why browser vendors use third party text
renderers...

It was theoretically possible that this codepoint triggers some sort of corner
case in UTF8 processing (why would it matter if a character is the first or
second in a string?), but it appears everything is fine and windows just does
windows things.

Thank you for clearing that up!

Thank you for clarifying - I wasn't sure if the OP was also talking
about an issue with the code editor. However, I think inclusion of
fonts in the LCL might make sense if it is found that system fonts are
lacking for popular platforms.

The LCL is (to my knowledge) linked in to applications generated with
Lazarus and never installed separately. Some toolkits for other
languages, installed separately, ship with (optional) resource files.
Compiling in the resources to every program which uses the LCL is a
bit different, but the same principle.

If anything that should be part of the application's setup, not of the
application itself nor of the LCL.
