I tested my font with ftview and it seems to work properly displaying all  
the glyphs in the file.  So the problem must be in my code that I use to  
render and such.  I am following the tutorial quite closely so I'm not  
sure what isn't working correctly.  Here is a sample of my code.  (Error  
checking is left out.  I do check for returned errors.)

#include <ft2build.h>
#include FT_FREETYPE_H

int main(int argc, char* argv[]){
        
        FT_Library  library;   /* handle to library     */
        FT_Face     face;      /* handle to face object */
        int error;
        size_t n, num_chars;
        wchar_t * text = L"Testing";
        num_chars = wcslen(text);

        error = FT_Init_FreeType( &library );
        error = FT_New_Face( library,
                         "..\\..\\font\\unifont.pcf.gz",
                         0,
                         &face );
        error = FT_Set_Pixel_Sizes(face, 0, 16);

        FT_GlyphSlot  slot = face->glyph;  /* a small shortcut */

        for (n = 0; n < num_chars; n++ )
        {
		error = FT_Load_Char( face, text[n], FT_LOAD_RENDER | FT_LOAD_MONOCHROME  
);
                if ( error )
                continue;  /* ignore errors */
        
//              pen_x += slot->advance.x >> 6;
        }

        return 0;
}


I run it in debugging mode and look at the slot->bitmap.buffer and it  
doesn't match the characters that I am trying to load.

Thanks for your help.
