If you're talking about interactive use, Emacs has a method based on
searching the Unicode character database.

LaTeX math notation has a number of potential pitfalls.  In
particular, the sub-/superscript notation can be applied to anything,
not just characters that happen to have *script versions in Unicode.
Also, not everything that seems to a character in LaTeX necessarily
has a corresponding Unicode character.
