I do - at least partly. ;-) There are two issues there:

1) You must differentiate between different internally used ways how to
store Unicode characters. Especially, you need to ensure that UTF-8 source
is translated to a "proper" widestring during compilation.

2) You need to know the charset used for video output and translate on the
fly where needed. The notorious "Video unit rewrite" (still unfinished
because of other activities like release coordination ;-) ) is supposed to
provide such a possibility (together with an option to use regular
Write(Ln) after incorporating the rewritten unit Crt).
