Alternate glyph for ۇ

[KrasnayaPloshchad]

The letter ۇ has a special shape in Uyghur and Kazakh texts, in this case dammah looks like comma. But Amiri does not support this form when I specified these languages.

Here are some materials for this design:

An article about Uyghur type design, you can see on 1957 book Köngül Arzusi this form is already appearing in Uyghur

Recently I found there is another implementation for this. Scheherazade/Lateef doesn’t making this variant work as localized form, instead, they used cv50 feature to transform its dammah as filled shape. I think this can be seen as model, but ssXX feature would be better choice.

Here is my proposal for Damma alternate, based on Amiri Regular, and you can create alternative glyph for ۇ based on this.

What about this?

That looks not desirable. In a Uyghur book Köngül Arzusi printed in 1957 the filled damma looks as this:

In this case the begining looks rounded, i.e. more like western comma. Also appearing in modern Uyghur books and newspapers printed in Xinjiang. In some Uyghur signages I saw another design as this:

Both these shapes appeared very common in Xinjiang, and none of them having crescent shaped design for filled damma as you made.

I think my glyph is still recognizable and fits well with Amiri’s design, so I’m keeping it until native readers complain.
