uli Can you elaborate on what you mean by that?
Yes. What I was thinking was that maybe a key combination can be used to enable a further graphics mode.
What I mean is: lets say you hit CTRL-ALT-' (the key to the left of one in the keyboard, for example). That enables a special "graphic mode" (with a different cursor to signal you're in that special mode). When you enable this mode, instead of the regular characters, you get a complete new set of characters from the same key combinations, that are mapped to a different place in Unicode. These could be the characters from the Pixel Art section, for example. This mode could be disabled by hitting the same key combination or the ESC key.
The idea is to give easy access to more characters, without resorting to obscure key combinations, like the Alt-codes of the past. Because there's no easy way to use more characters from Unicode's higher planes than the ones already mapped to the keyboard. If I don't have a German keyboard, and I want to write an eszett, what can I do? This is normally solved with Alt-codes. It's a pretty obscure solution.
But it's just an idea. I don't know if it's possible of practical.
(Btw: when thinking about this, I remembered the Spectrum, where the cursor was modal and would change to allow you to type BASIC commands by just pressing one key. In the "command mode", pressing [P] will give you "PRINT". and it's this modal nature that made me think of this idea. But modal interfaces could be difficult to understand, if not implemented correctly).
