Mongolian should already be handled by the Arabic shaper due to it's similarity. There may be some differences that we don't handle though. Do you have a test case that's failing?
The Arabic shaper is based on code from Harfbuzz. Looks like they have a few Mongolian specific features that we don't. Maybe a place to start? https://github.com/harfbuzz/harfbuzz/blob/2dda6dd744b192616c65ca4aa5fce8e90fd0ff30/src/hb-ot-shape-complex-arabic.cc#L348
I need Mongolian font support in fontkit. I don't know how to do it. The Mongolian font used the 5 features: isol, init, medi,fina and rlig.
