Yeah, I only realized what was going on when I saw this error message...
Unfortunately this isn't working when you are using SynEdit (I didn't
try to understand where this verification is done or why it isn't
working, though).
SynTextDrawer calls IsDBCSLeadByte which access WidgetSet and this
doesn't trigger that message if WidgetSet isn't set.

Yeah, being the curious guy I am of course I read the file as soon as
the message showed ;-)
I've read something about it in the wiki entry about conversion from
Delphi to Lazarus, but this still wouldn't explain that I needed to
use it in my .lpr and why I have to.

I may be exagerating a bit ;-)
But my question remains: why doesn't Forms or Controls use it already
(since they will certainly neeed it) so one didn't have to "use" it
explicitly?
Cheers,
Flávio
