It does exactly what the docstring say.  What you don't seem to understand
is that a char can be bound to self-insert-command via a keymap binding that
doesn't mention that char.

Basically, it's often easy to find the reverse mapping of a keymap (i.e. the
inverse function, if you think of the keymap as a function from keys to
commands), but it's not always that easy.  There are many special cases.

I'd ask a different question: why do you start from a keymap and use
map-keymap on it, rather than start with `charset-list' and generate the
complete set of valid chars from it?
