Greg Haerr:
2) with fontforge I have open the .bdf and I have see that first
cyrillic symbol is the 1024 (unicode). I have try to show this only one
but I get an error (see attach char_utf8.txt). Why?
Pretty strange. You might try turning off background painting
with GrSetGCUseBackground(FALSE) before the GrText
call, we need to debug why a drawhorzline call is being made
for text, I think its for text field area clearing... a gdb stack
trace would be a good idea, there is something wrong here.
On a first test with GrSetGCUseBackground(gc, GR_FALSE); the application
work but not show the symbol (also with unsigned short type).
Could have something to do with the converted builtin bdf
file. Make sure you're running CVS code by the way, since
there were some bugs fixed in the convbdf program some
months ago.
cvs status convbdf.c say to me is up-to-date (rev 1.4) and the root of
repository I'm using is :pserver:[EMAIL PROTECTED]:/usr/cvs.
I have made only few test on the target device with old source, the
others I have made was on a pc, source from cvs and upon X11.
I have edited the DejaVuLGCSans.c and DejaVuLGCSans.bdf: the ascii
representation of char 1024 is the same (also the 1025 and 1026) of the
symbol show by fontforge: it seems to work correctly.
I have wrote a win32 application starting from mtest.c (see attach)
where I call MwExtTextOut directly but result is the same: symbols from
UTF8 coded file are wrong.
Both application not draw the symbol 1024 but everyone show different
symbol reading from the same file.
Furthermore, I have see that I read 20 char from UTF8 file but only 8
are showed.
I attach the source of both application, win32 and nanox.
