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.
