Footnote/index oddity

[Edward M. Reingold]

Apologies for the long introduction to my question, but the details are
important. When the 2nd edition of my book was prepared in 2000/2001 index
entries such as

\index{Dikshit, S. Balkrishna@{D\^{\i}kshit, S. B\^{a}lk\d{r}ish\d{n}a}}

produced an entry in the .idx file of

\indexentry{Dikshit, S. Balkrishna@{D\^{\i}kshit, S. B\^{a}lk\d{r}ish\d{n}a}}{298}

whether or not the \index command was in a footnote or the text.

Now, in preparing the 3rd edition, I find that the \index command produces
exactly the above if the \index command is in the text, but produces

\indexentry{Dikshit, S. Balkrishna@{D\^{\i }kshit, S. B\^{a}lk\d {r}ish\d {n}a}|hyperpage}{304}

if the \index command is in a footnote; of course this results in split index
entries that should be combined.

The .log and .ilg files in 2000/2001 contain

and

This is makeindex, portable version 2.12 [26-May-1993].

respectively, while for the cuurent runs (for the new edition) the same logs
have:

and

This is makeindex, version 2.14 [02-Oct-2002] (kpathsea + Thai support).

respectively.

Question: What is the cleanest way to get all of the index entries to be
identical, footnote or not? The same problems occur whnever there are
diacritical marks, Chinese characters, etc. in the index entries for both
footnotes and main text.

Use the 'index' package instead of 'makeidx'.

That package conflicts with the (many, many) other packages I need.

\index reads its argument in verbatim manner, especially the catcode
are changed. Example: \i is read as character '\' with catcode 12
(other) and 'i' with normal catcode 11 (letter). Therefore you get,
what you expect.
Inside the argument of \footnote or any other macro the whole
argument is read with \index and its argument. Thus if \index is
executed later, the catcode changes haven't an effect, because
the argument of \index is already read. Example: \i is now a
macro. Macros whose name consists of letters are written with an
appended space: '\i '

* Manual solution:
Use \string, if \index is used inside arguments:
\index{...\^{\string\i}, ...\string\d{n}...}

* Or redefine \index that the argument is no longer read as verbatim:
\newcommand*{\OriginalIndex}{}
\let\OriginalIndex\index
\renewcommand*{\index}[1]{\OriginalIndex{#1}}

* Or use XIndy, AFAIK it deals with such kind of problems.
