Alternative character sets for year-suffix?

This may be one for Elena, maybe. Are there non-English styles (or
English styles, for that matter) that use something other than a-z
other for year-suffix disambiguation? After a lot of fretting today,
I have solved the problem of applying year-suffixes with arbitrary
characters sets. Now I’m curious whether the problem actually exists.


I haven’t encountered this problem–I think this is not relevant for
Russian, but I can’t speak for other languages. :slight_smile:
