If we want sorting in index according to the Swedish sorting rules we usually pass -C utf8 -L swedish to xindy.
The key problem I found is that we are not able to pass multiple nested parentheses on the input side, the output side, e.g. markup-locref, is having no difficulties.
So the mentioned strategy is fine, to turn off generating of the second command, \hyperpage, a command used by the hyperref package, which is passed to xindy, otherwise we would need to handle it anyway by external tools.
Our problem splits into two parts: if we use one single command after the @ operator (typeset material) or after the | operator (index references).
- After the
@ operator I use a new single command where I can use any typeset material, in the following example I pass colors, mathematics, font styles, indentation and other material to the index entry. It is not used for sorting, so xindy passes it untouched.
- However, if we use the
| operator, we don't use backslash in the command and we must notify xindy what it is as it is becoming a part of merging, sorting, grouping, tagging etc. We create our own xdy file and we use define-attributes and markup-locref there. Thanks to the filecontents package it is easy to have these definitions in the main TeX file.
That solves our two-part problem for most indices. I enclose a simple example and a preview of the first page. I run these three commands to process the example.

Next examples of indices
An index is just regular typeset material as any other, usually generated from the idx file containing many \indexentry commands to the ind file, it consists of the theindex environment with a bunch of commands, typically with many \item, \indexspace, \lettergroup and \lettergroupDefault, which we can redefine, if needed.
I enclose snapshots of my work. The first example contains glyphs of the specific font which we are referring to (picture on left), the second example contains CJKV glyphs, to be more specific, those are kanjis used in Japanese (picture on right).
