1. collect utf-8 text in Coptic (DONE)
2. Find Coptic unicode fonts, if you can find one similar to the
typewriter font used in books it will make training easier
I tried but couldn't find such font. There are not that many Coptic
fonts to being with.
Can't I just extract few samples of each letter from the old books?
3. train a model with these and then finetune it with line images and
matching ground truth
I think I got this one.
After extracting sample letters. arrange them randomly into separate
lines (image for each line) and provide the text in a file with similar
name.
That's a good idea but since I am trying to train for reading old books,
how can I account for things like slight page tilt during scanning for
example?
Also while at it, is there a tool I could use to split book pages into
separate lines so that I can give it as part of training (along with
it's text of course)

I am trying a test training for coptic for tess4, will let you know
where to access traineddata.
You can train using utf-8 textand unicode optic fonts.

Thank you ShreeDevi for both moheb's link and the one below.
The current one uses Tesseract 3 and according to the author:
"Recognition quality of Coptic texts containing old fonts will be
very poor, depending on the trained data."
I will get in contact with him to see if we can use the other link
you provided
https://github.com/OCR-D/ocrd-train
<https://github.com/OCR-D/ocrd-train>
To train Tesseract 4.00
Thank you very much

See http://www.moheb.de/ocr.html <http://www.moheb.de/ocr.html>
It provides a traineddata file for Coptic for use with tesseract
version 3.

Hi,
I belong to a group who study an old Egyptian writing system
called "Coptic".
It's based mostly on Greek (with some variation).
Big majority of books written in Coptic where during the last
century and were mostly the same [typewriter] font.
Here is a sample picture:

And sample book:

<https://archive.org/download/pistissophiaopu00petegoog>
We need to add Coptic to languages supported by Tesseract but
not sure how.
I tried following this document
https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00
<https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00>
but it's very difficult to understand.
We need someone help us with the initial setup so that we can
dedicate our man power to training the system.
We are none profit group so we are hoping for free help but
we would also consider paid help since the alternative is
hundreds of hours of man labor to digitalize just few books.
Thanks everyone for contributing to this awesome project
