Phillipe By "relative ordering" I did not mean relative collation weights but the order in which these combining characters are usually entered relative to other characters and each other - and the order relative to each other in which they should be stored in a string. The current CCCV weights for these characters mean that they can end up in a bizarre order which makes no sense, serves no useful purpose and complicates rendering and collation .
The only thing I did mention specifically about collation is that 0F7E 0F82 and 0F83 should generally treated as equivalent for collation purposes. Culturally correct collation rules for Dzongkha and Tibetan are *very* complex when compared with those for any other language I know of and I don't want to get into all that here. - Chris
