[OpenJDK 2D-Dev] [PATCH] support Mongolian and FVS(Mongolian Free Variation Selector)

[Nakajima Akira]

Hi Steven.

========================================================
https://www.unicode.org/L2/L2018/18168-script-rec.pdf
from Page.2
"The entire model for Mongolian is still under discussion"
========================================================

Thanks for giving me information.
I don't know when Mongolian model will be fixed (1 year, 2 years, or 
later...).

Anyway, Windows and FireFox display Mongolian in current unicode ver.
But Java does not display about Mongolian glyph transformation.

I guess that it is better to make it possible to display as same as 
Windows/FireFox.

This patch seems to display as same as Windows/FireFox.
And this patch's modification depends on harfbuzz.
Please anyone let me know expected trouble by applying this patch.
