You are inconsistent here. You thanked me for disunifying COPTIC
LETTER KHI from GREEK LETTER CHI, and for disunifying COPTIC LETTER
RO from GREEK LETTER RHO. Previously, people argued that they shared
the same meaning, the same appearance, the same name, the same
typographical behaviour and the same origin. It took many years of
struggle to get the committees to accept the disunification. In point
of fact, CHI RHO and COPTIC SYMBOL KHI RO don't share the same
appearance, which is one of the factors behing the disunification in
the first place.
>I find this disunification abusive.
You are mistaken. You are, however, free to choose to put either CHI
RHO or COPTIC SYMBOL KHI RO in your texts. The International Society
for Coptic Studies recommends the use of COPTIC SYMBOL KHI RO.

That analogy doesn't work. The Coptic glyph for KHI RO is pretty much
unsuitable for most Latin and Greek contexts.

It was a question of consistency.

We're not going to do that. It would introduce inconsistency in
representation of Coptic text.

In its current form it is a symbol for a word which may be
represented in a number of ways, as I indicated yesterday: JO(E)IS,
J_S_, JAEIS. JAIS, C_S_, CO_S_, CS__, O_S_
It may be the case that symbol is never found without an abbreviation
bar. That does not mean that the abbreviation bar should be built

That isn't true. We knew perfectly well. SHIMA SIMA may not be an
obligatory ligature, and would be the only ligature in the whole set.

It may not "mean" anything without the bar. It is nevertheless an
element of the writing system. The encoding model we chose asks the
user to type the bar manually in all instances where an abbreviation
bar is desired. That is consistent behaviour, which is better for
Coptic text encoding.
