Whenever I need to find a Unicode glyph, I use Glyphy.jl:
and then I can copy/paste from here.
Of course, the glyphs can only be displayed if you have the fonts/fallback fonts around that include them. So you probably won’t see any glyphs for the Zanabazarin Dörböljin Useg script, for example:
julia-1.10> glyphy("zanabazar")
11a00 𑨀 zanabazar square letter a
11a01 𑨁 zanabazar square vowel sign i
11a02 𑨂 zanabazar square vowel sign ue
11a03 𑨃 zanabazar square vowel sign u
