When did it work?

AFAIK they're all characters (my use of `symbol' was in the Lisp sense
of symbol as opposed to integer, string, cons, float, ...).
> What makes the distinction?
The code that turns GUI events into Lisp events, mostly. The general
rule is that keys which should self-insert get turned into
character-events, while other (special) keys get turned into symbol-events.

Unicode has nothing to do with it, no.
