Oh? What "important" scripts aren't on the Roadmap? The "important"
(national) scripts have all been encoded; Tibetan, Sinhala, Ethiopic,
Thaana, Myanmar, and Khmer were among the last "national" scripts
which were encoded. Of course we add Arabic characters for Urdu and
Georgian and so on as they appear.

I suppose. But if Phaistos were deciphered I would be pleased to encode it.

Oh no! We're found out!

I imagine the KangXi characters have been encoded by now. Egyptian is
on the list but is a big job. You may know I've done a fair bit
towards encoding Egyptian.

They appear in a great many travel guides as meaningful characters.
Research on things like this continues.

Ah. I didn't track your use of the word "fancy". Still it's
interesting to note that Budge printed red hieroglyphic text with a
bold black line above the entire text which was red in the original.
Possibly a cause to encode "BEGIN RUBRIC". (It's never neat and tidy,

What is "inclined Cyrllic Be"?

Copticists agree that this unification was false, and the paper N2444
Coptic supplementation in the BMP at
http://www.dkuug.dk/jtc1/sc2/wg2/docs/n2444.pdf has won the day and
it is agreed that the two scripts be disunified and the Coptic
letters answering to the Greek be added to the standard in future.
