All the win32 widgets are coded to use only the System font, unless
you send them a message (or change the initialization code) to
use your own font. The encoding field doesn't have anything
to do with this.
What do you mean by the bounds problem?
I mean that the text was drawn upon the window.
Window with editbox seem to use the system font while text use the
builtin font so I get a little window with big text over it.
Does this occur
normally without your font being builtin? (or the field set as above?)
If I unset the fontprocs->encoding (leave it to ASCII) all works ok: the
text is inside of the editbox and window but only the latin symbols are
showed. If I set it to UC16 I get the effect as mentioned above.
Now I make my test direct on the target that use a c++ wrapper class
(developed by G. Brugnoni): inside it the SetWindowText is used.
So I have modified the win32 demo by adding an editbox but this one not
show the utf8 text. I attach my example.
