There's an Apple II clone from Taiwan which apparently forgoes the text mode and just has a graphics mode because it's simpler that way to render Chinese writing.
It had a 16K ROM, of which 12K is a BASIC interpreter, which leaves 4K for whatever else. How did those 4K accommodate a Chinese font on top of whatever else it needed to do?
(I have the idea it might've done some kind of compression, for example 說, 話 and 語 all have identical left-hand sides. Hard to say if that's worth doing though.)
