Full picture
Meaning - Glyph - Codepoint
Old ChurchSlavonic:
Narrow Yest (regular form) - very narrow halfmoon - 0404/0454 (ambiguous) and
0415/0435 (probably wrong glyph will be rendered) (there are no
certain codepoints)
Broad Yest (special form, initial, plural disambiguator) - broad
halfmoon, identical
to Ukrainian Ie or maybe somehow grater (broking baseline) - 0404/0454
Modern imitation of Church Slavonic, or really old texts, or texts
where hard to distinct Broad and Narrow Yest:
Ambiguous Yest - identical to Ukrainian Ie or maybe like Narrow Yest
(in old-style font) -
0404/0454 sure
Modern languages:
Ie - rectangle capital / closed rounded small (identical to Latin) - 0415/0435
Ukrainian Ie - identical to ambiguous Yest - 0404/0454

So there are two steps. First. Required. Separate codepoint for Narrow
Yests. It is just impossible to work with ChurchSlavonic texts without
these. Because: wrong glyph is rendered almost always (you must
understand, we cant hope on language detection, cause the text
contains certain the mix, old text with modern translation) - or -
there is no way to show  Broad Yest at all.
Second. Optional. Separate codepoint for Broad Yests. That's only
necessary if one part of text contains the ambiguous Yests (coded as
now, 0404/0454, without changes!) but other part contains the Broad
Yests and the author can/wants to show this feature.

Am i the only man in the world who think that Unicode is poorly
adapted for ChurchSlavonic?
