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, ...).

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.
