f you use a font that makes those Unicode characters look like they did on their original platform, there is no issue. But a given font can only emulate one platform at a time. You're not going to get a C64 and PET/VIC-20 frankenstein of a document. Take your pick: do you want it to look like C64, or do you want it to look like PET/VIC-20? Choose your font accordingly.
Round tripping plain text to a mix of devices is not a goal, just as round tripping plain text Han characters to a mix of regional variants is not a goal.
You (Piotr) need to demonstrate that for a single display, on a single device or emulator for a single device, you cannot get the correct appearance by systematically using a device appropriate font.
If a device supports "shifted" modes, then a device appropriate font may change based on the shift status.
Only when that accommodation fails to produce the correct appearance is there a case for further disunification.
The diagonal connector issue satisfies this requirement, but as far as I have been able to understand, the block characters do not.
