Re: [ft-devel] FT_Get_Char, FT_Get_Next_Char

I used the example code from the documentation:
http://freetype.sourceforge.net/freetype2/docs/reference/ft2-base_interface.html#FT_Get_First_Char

I'm not sure the do{} while() your proposed would change anything (I'm getting 
0 as a charcode after the loop).
