Use key.unicode instead of key.sym? Not sure if it already handles things such as shift and etc, but it's a start...

EDIT:
Misread the post.

Generally, you'd have a table of SDL_Rects you index into to select where in the bitmap that character resides:

Slightly pseudo-code:



SDL_Rect glyphBounds[256];



// load into file

std::ifstream fs( "bitmap_font.txt" );

for ( int idx = 0; idx < 256 && fs >> glyphBounds[idx]; ++idx )

    ;



// draw:

std::string str = "Hello";

int x = 0, y = 0;

for ( int idx = 0; idx < str.length(); ++idx ) {

     const SDL_Rect& r = glyphBounds[str[idx]];

     draw( x, y, bmpFont, r );

     x += r.width;

}
