input methods for mathematical glyphs

[Leo Butler]

Hello,

I have, for years, used abbrevs for entering greek letters (and several
other commonly-used symbols in math). As I have learned how to use
latex's support for other unicode math glyphs, I can see that my old
solution does not scale and I would like to find an input method to
easily input something like:

#+begin_src latex
Let $𝒯 ⊂ 𝐑$, $𝒯 ≠ ∅$, be a null set...
#+end_src

I used C-x 8 RET to do this. I am ignorant of any input method that
would do what I want (ucs may be the closest, but it only uses 4 digit
hex, and who wants to memorize 4-5 digit hex numbers?)

Suggestions or thoughts?

TIA,
Leo
