If that's the use case (I don't think you described it before), then
we indeed need a convenient facility to browse character glyphs.  But
that facility should allow to specify additional information, such as
the script name, or block name, or the base character, otherwise you
are likely to give up due to the sheer number of characters to view.

No, you need to type much less.  A codepoint, if you know it, is at
most 5 characters, and for name completion, typing something like

  C-x 8 RET greek <TAB> <TAB>

(all in all 10 characters) will have the completions buffer pop up.
Each completion candidate has the character glyph displayed right next
to it, so you could use that for finding the one you are looking for.
