N2463 also maps twelve characters from ISO 10574 that have been disunified since 2002, namely: 04/06 CYRILLIC SMALL LETTER KURDISH QA is now U+051B CYRILLIC SMALL LETTER QA 04/09 CYRILLIC SMALL LETTER EL WITH MIDDLE HOOK is now U+0521 CYRILLIC SMALL LETTER EL WITH MIDDLE HOOK 04/10 CYRILLIC SMALL LETTER MORDVIN EL KA is now U+0515 CYRILLIC SMALL LETTER LHA 04/14 CYRILLIC SMALL LETTER EN WITH MIDDLE HOOK is now U+0523 CYRILLIC SMALL LETTER EN WITH MIDDLE HOOK 05/06 CYRILLIC CAPITAL LETTER KURDISH QA is now U+051A CYRILLIC CAPITAL LETTER QA 05/09 CYRILLIC CAPITAL LETTER EL WITH MIDDLE HOOK is now U+0520 CYRILLIC CAPITAL LETTER EL WITH MIDDLE HOOK 05/10 CYRILLIC CAPITAL LETTER MORDVIN EL KA is now U+0514 CYRILLIC CAPITAL LETTER LHA 05/14 CYRILLIC CAPITAL LETTER EN WITH MIDDLE HOOK is now U+0522 CYRILLIC CAPITAL LETTER EN WITH MIDDLE HOOK 06/03 CYRILLIC SMALL LETTER ER KA is now U+0517 CYRILLIC SMALL LETTER RHA 06/08 CYRILLIC SMALL LETTER KURDISH WE is now U+051D CYRILLIC SMALL LETTER WE 07/03 CYRILLIC CAPITAL LETTER ER KA is now U+0516 CYRILLIC CAPITAL LETTER RHA 07/08 CYRILLIC CAPITAL LETTER KURDISH WE is now U+051C CYRILLIC CAPITAL LETTER WE There is a clear precedent here that the unifications of N2463 are not necessarily the final fate of any of these characters. If the О Е letter for Selkup should be disunified from U+0152/U+0153, then a proposal needs to be submitted calling for the addition of the two letters to the UCS. It is worth noting that N2463 also decomposes four characters using U+0335, a practice which hasn't been used for decompositions since Unicode 1.1. I also don't understand the mapping of 04/05 CYRILLIC SMALL LETTER CHECHEN KA and 05/05 CYRILLIC CAPITAL LETTER CHECHEN KA into <U+043A CYRILLIC SMALL LETTER KA, U+030A COMBINING RING ABOVE> and <U+041A CYRILLIC CAPITAL LETTER KA. U+030A COMBINING RING ABOVE>, respectively. Is the character shown in ISO 10574 just a glyph variant of this combining sequence? —Ben Scarborough
