[Not exactly an answer]

I use a number of things for such
1. Google
2. Xah Lee’s excellent pages which often fit my brain better than wikipedia:
   http://xahlee.info/comp/unicode_index.html
3. emacs’ function ucs-insert recently renamed to insert-char
   ie [In emacs] Type Alt-x insert-char
   After that some kind of TAB-globbing (case-insensitive) works
   I wont try with Cap (because the number of *CAPITAL* is in thousands!)
   eg alphaTAB gives nothing. However *alphaTAB gives a bunch.
   Narrow to "greek alpha"TAB and you get a bunch


The fact that we should have a series of levels for char-input from
most general and unergonomic (google) to most specific and ergonomic (special purpose keyboard) Ive tried to talk of as 7 levels near end of
