To decide if something is to be prettified, there's
`prettify-symbols-compose-predicate' which is
`TeX--prettify-symbols-compose-p' in AUCTeX.  Basically, that looks at
the char after the found symbol to decide if it is to be prettified.

Examples:

  \alpha     ;; prettified
  \alphafoo  ;; not prettified cause foo is still part of the symbol
  \alpha2    ;; prettified because a number is not part of a macro
  \|U        ;; not prettified because the U could be part of the macro
