Yes, I have and ucs, too.

If I do

M-x list-input-methods RET

search for and select TeX, the *Help* buffer is populated by a large
number of supported glyphs. When I search for 𝒯 (or 𝐑), it is not
found. It looks like there is some large, but limited number of glyphs
that are supported, but many are not.   ;-(

Suggestions?
