Is it possible to use the Unicode superscript and subscript parentheses as
superscript and subscript operators? That is, ⁽…⁾ having the same function as
^{…}, and ₍…₎ as _{…}.
It might be something like the following, but somehow bundling the last part of
\letcharcode into a command.
\appendtoks
\catcode`⁽=\activecatcode
\letcharcode `⁽ ^{
\catcode`⁾=\activecatcode
\letcharcode `⁾ }
\catcode`₍=\activecatcode
\letcharcode `₍ _{

{\catcode`⁽=\activecatcode\letcharcode`⁽=\FancySuperscript
\catcode`₍=\activecatcode\letcharcode`₍=\FancySubscript}
