Well, this is why it would be optional, an extension of the default
behaviour, only for those who want it.  At least until someone will do
bigger makeover.

Hmmm... this sounds kind of like (on emacs 26.2):
'M-x list-charset-chars RET unicode-bmp/sip/smp/ssp RET'.
Assuming someone knows hex code or part of it, simply doing
'isearch-forward' will bring him to the neighbourhood of the character
he is looking for.

This sounds more like bigger(?) upgrade of 'insert-char', rather than
a new command.
