Excellent news – the chap I commissioned to type up the Coptic text of the fragments of Eusebius in that language has done so and I have the file. He did an excellent job. In fact he inlined extracts of the page images, and then typed underneath in unicode. He said:
I’ve used a Unicode font called Keft. You can download it from http://www.evertype.com/fonts/coptic/ if you don’t already have it.
I don’t know if there is a “standard” Coptic font to use, nor how he did his data entry — is there perhaps a Coptic keyboard? All the same, I am very glad.
I’ve now passed the file to the Coptic translator for comment, and since she is a little technophobic I am reasonably confident it will blow her socks off! Very nice piece of work, very quickly done. (Indeed I was so pleased I added a bonus for quick completion).
