I am preliminarily trying to work with creating a couple of indexes with xindy in a XeLaTeX file. One index will be the normal index about names, and I may disturb the list later on. A second list is about transliterated words
As I use ancient Egyptian hieroglyphs transliterated, I need to create an index being ordered in a certain order:
Unicode A722 should be the first letter, then Unicode A357+i as second letter, Unicode A725 as third and so forth (As those signs do not appear in the majority of the normal fonts, I prefer to give the code out of it).
The order is the usual academic order, but it is completely artificial, and not officially supported by any of the languages normally used in XeLaTeX (unless Ancient Egyptian has become a modern language and I did not know about it...).
Is there any information online in order to create a new ordering system for the index, or anyone on the list has any suggestion about a way to proceed?
