I think multiple keys with the same name should be allowed for a
node/way/relation. AFAIK it’s only the editors that don’t currently let
you do this.

Almost any character could appear in regular data, unless it’s quite a
special character—say, rather appropriately, the unit separator (US,
ASCII 0x1f). The problem then is entering the special character.
Ultimately the user should not have to care what, or if a, separator is
used, and they would be presented with multiple values as appropriate
for the interface they are using.
A complex system that works is invariably found to have evolved from a
simple system that works.—John Gall
