@ZDL For Greek Unification to be truly Greek, it must include unifying the Cyrillic 'ш' and Egyptian '𓆷' and perhaps also Hebrew 'ש' Backwards compatibility!
Strangely, Unicode has unified the three first generations of Egyptian glyphs — hieroglyphs, Hieratic, and Demotic — together. Or, well, it pretended to. The transition covers over some three thousand years of literary cultures, and linear counterparts don't always exist. Coptic is separate, although there was an early attempt to unify it with Greek; didn't work out, so now Unicode has Greek-And-Coptic letters, and then separate Coptic letters.
On the other hand, most Brahmic scripts are very closely related syllabaries, and yet, Unicode hasn't seen it fit to unify those, let alone the hundreds of different forms of the Hindu-Arabic decimal digits that have proliferated in Asian scripts.
