Cyrillic letter "Ot", U+047F (upper case: U+047E), used in Old Slavonic texts, is graphically a cyrillic omega (U+0461 and, upper case, U+0460; equally archaic), with a "90-deg. clockwise rotated E" above it -- quite like one of the usual (current) glyph variants for upper case cyrillic "T" (U+0422), with some kind of hypertrophiated serifs.
Therefore, a possible decomposition of U+047F could be U+0461 U+036D, relying on the rendering mechanism to alter the shape of the diacritical "t" based on the base letter, and considering the "trans-script" nature of Unicode diacritics (I.e., you dont need a specifically cyrillic "t" diacritical for the same reason you dont need a specific cyrillic breve for russian short "i".) Not really a serious proposal, but what would you think? -- ____. Ant�nio MARTINS-Tuv�lkin | ()| <[EMAIL PROTECTED]> |####| R.
