Mongolian Vowel Separator (MVS) Ignored in Mongolian Baiti MS Font on Chrome in Windows 11

[KazunariTsuboi]

Description:

When trying to display Mongolian script on Chrome in Windows 11, I noticed that the Mongolian Vowel Separator (MVS) is being ignored. The font I’m using is Mongolian Baiti MS, and this issue occurs when displaying text on Google Chrome using the font installed on Windows.

Unicode strings: ᠶᠠᠪᠤᠯ᠎ᠠ

U+1836 U+1820 U+182a U+1824 U+182f U+180e U+1820

Issue:

The display changes when I use the exact same font as a web font. For testing, I referenced the TTF file with @font-face and displayed the text using the web font. Despite using the same text string and the same font, the final vowel shape affected by the MVS appears differently.

Expected Result:

The desired display result for Mongolian script should look like this.
