Issue

U+1123E KHOJKI SIGN SUKUN is placed inconsistently. Normally, after a vowel sign like -ā or -ai, the sukun is placed above and to the right of it. After independent vowels and ligatures that involve those vowel signs, the sukun is placed differently, or overlaps part of the ligature glyph. This is because the sukun-relevant anchor points are placed inconsistently and are missing from some glyphs.

I'm going to have to get some advice about how this should work - currently the sukun is placed in the same position as the nukta, so you get

I don't know if one or both of these are wrong.
