When typesetting equations with long exponents or high-numbered footnotes right before punctuation marks, the result is a rather awkward large space between the last letter and the punctuation mark:
\setcounter{footnote}{138}
{\Huge
$X^{\mathrm{red}}$, blah\footnote{}.
}
resulting in
Now, I'm not sure that this would actually look better, but is there an (elegant, i.e. no manually inserted negative whitespace ....) way to have the .
and ,
appear under the exponent?
EDIT: To avoid confusion: I'm interested to find out whether it's possible to have the ,
in $X^{\mathrm{red}}$,
treated like the 0
in $X_{0}^{\mathrm{red}}$
. Whether this behaviour is advisable is, of course, an entirely different question!
