If so, it calls the DOS/V 'read font' function to get that character's bitmap, and instructs the drawing code to draw 16 pixels from offset 0 of that bitmap, rather than 8 pixels from the system font bitmap at a given offset. There are similar checks in the optimised monospaced text drawing code, allowing characters to be 8 or 16 pixels wide.}} (NB.
