I think there are two d shapes.
I think there are three m shapes, maybe four.
I think there are macrons. Which transliteration alphabet includes them?
I think l is misunderstood.
There are other matters, as well, ones that go beyond shape, but it takes more data to explain them and I can't do that during the workday.
Part of the problem is that many researchers (including most of those who have presented "solutions") have little or no experience with reading medieval text. Some are not even familiar with calligraphy. It takes a certain amount of experience to interpret the shapes within a medieval context.
It's too soon to standardize.
