I'd tend to agree that key-translation-map is more suitable, although using
function-key-map would have the advantage that people's old bindings like
(global-set-key [241] 'foobar) would still work.
OTOH such bindings are fundamentally wrong IMNSHO (although it's the "only"
thing that works in older Emacsen).

How about `last-input-event' ?
Of course, that won't work if the key looked up in key-translation-map is
the result of a mapping in function-key-map rather than a key directly hit
by the user, but it shouldn't be too much of a problem.

Since it's supposed to return a sequence of events (array or string),
I guess an empty string is fine, although nil might work as well. I'm not
sure how well the keyboard.c code (it's quite brittle) deals with such
a case, but there's no obvious reason why it should fail.
I looked at how C-x 8 works, but that code pre-computes a keymap instead of
using a function.
