I don't think it is either batty or crazy. People can certainly use
the PUA to interchange text (assuming that they have downloaded fonts
and keyboards or some other input method beforehand), and
it
can definitely serve as a proof of concept
. Plain symbols — with no interactions between them (like changing
shape with complex scripts), no combining/non-spacing marks, no case
mappings, and so on — are the best possible case for PUA.
It is kind of a bummer, though, that you can't experiment (easily? or at
all?) in the PUA with scripts that have complex behavior, or even
not-so-complex behavior like accents & combining marks, or RTL direction
(here, also, am I speaking true? Is there a block of RTL PUA also? I
guess there's always RLO, but meh.) Still, maybe it doesn't really
matter much: your special-purpose font can treat any codepoint any way
it likes, right?
