: return MwExtTextOut(hdc, x, y, 0, NULL, lpszString, cbString, NULL,
: MWTF_UTF8 );
:
: Debugging, the function is called but the symbols are still wrong (the
: same as MWTF_UC16).
You should write a test program that displays text in a window
directly using this same function. If it works, then there are
issues with how the edit box control stores text. Otherwise,
there are still other issues.
Starting from pcfdemo.c, I have write builtinfont.c that use GrText
function that also call GdText function: I'm not be able to see the
right symbols but I have some new questions:
1) UTF8 use 1 2 and sometimes 4 bytes for one symbol: I use a char array
for store the text file. Is this correct? (see attach for source code)
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?
Tnx.
Regards, Cristian
