[Ftgl-devel] FTGL has problems with some cyrillic characters

[Petko <pdi...@gm...>]

  Hello , everyone ! I have a very strange problem with FTGL . I set up 
a polygon font to Ariel, since its a standard font , but I'm having a 
problem displaying SOME of the Cyrillic characters . For example the 'a' 
doesn't display and breaks the rendering sequence . Has anyone had a 
similar problem ?
PS: I'm on ubuntu with FTGL from the repo-s which is 2.1.3 .. I should 
probably update the library . Still any help would be appreciated .

I thought I'd seen somewhere that the last version was 3.x.x but , I 
guess I was wrong , the 2.1.3 is the last stable (according to source 
forge) .
  Here's a screenshot with my test on all characters cyrillic 
(bulgarian) + latin :

(I guess I was wrong that a broken character breaks the rendering 
sequence or it just happened in some other circumstances ) . The same 
result comes out with 5-6 more fonts by the way , so it should be an 
FTGL problem .

Ok , sorry for triple posting , but I figured it out to some extent : 
The problem was caused by calling the font->Advance(some_string) outside 
of the display function . That resulted in FTGL omitting the letters in 
some_string later on when I tried to draw them . I worked around that by 
initializing a separate identical font2 which I use to draw in the 
display fonction .
