To those whom it may concern:
Silver has a whole lot of glyph ranges, so I consider it to be easier to load it dynamically.
So you would add Silver.ttf to your Included Files, and then do the following on game start:
globalvar fnt_silver;
font_add_enable_aa(false);
fnt_silver = font_add("Silver.ttf", 14, false, false, 0, 0);
Then you can do draw_set_font(fnt_silver) and GameMaker will load the glyphs when you first use them.
