Question

On some fonts, I can’t get SDL_TTF to render some glyphs (such as …), even when I know they are present (if I use the same font in, say, gedit, it works fine).

Makefile:

test: test.c
    gcc -o test -ansi -pedantic -Wall test.c `sdl-config --cflags --libs` -lSDL_ttf

Example (test.c):

#include <SDL/SDL.h>
#include <SDL/SDL_ttf.h>

int main(int argc, char *argv[]) {
    SDL_Init(SDL_INIT_EVERYTHING);
    TTF_Init();

    {
        SDL_Event ev;
        SDL_Color color = {255,255,255};
        SDL_Surface *win = SDL_SetVideoMode(640, 480, 16, SDL_HWSURFACE | SDL_DOUBLEBUF);
        TTF_Font *drawfont = TTF_OpenFont("./ProggySquareSZ.ttf", 22);
        SDL_Surface *text_surface = TTF_RenderUTF8_Solid(drawfont,"…",color);
        SDL_Rect r = {10, 10, 0, 0};
        SDL_BlitSurface(text_surface,NULL,win,&r);

        SDL_Flip(win);
        while(SDL_WaitEvent(&ev)) {
            if(ev.type == SDL_QUIT) break;
        }
    }

    return 0;
}

Answer 1

This font has no ….

Name: ProggySquareTTSZ
Supported Unicode Blocks
    0x0000 - 0x00FF   ANSI

A horizontal ellipsis has U+2026 code, it more than 0x00FF(255).

Probably you see … in gedit because in some operating systems and software, if a certain character is not found in
the font, it’s being replaced with same from more similar font, installed in the
OS, and then displayed.
