Issue: InDesign does not support Mongolian vertical text direction from left-to-right.
Version: InDesign 2019, 14.0.2 x64
1. Place or paste Mongolian text into an InDesign text frame by using the attached Word document
2. Skew the text frame 90 degrees (as done with vertical Chinese and Japanese).
Expected result: Please see the attached Word document and screenshot.
Actual result: Notice that the vertical text direction is right-to-left and not left-to-right. Even if the text frame is skewed in the opposite direction (minus 90 degrees) the text is just mirrored and thus not readable.
Test files and screenshot: They are attached. If need be you can download the Google Noto font called Noto Sans Mongolian that we used.
