[Message part 1 (text/plain, inline)]

Rendering Traditional Mongolian Scripts in Emacs are not perfect:
Have a look at following text:
ᠮᠣᠩᠭᠣᠯ ᠪᠢᠴᠢᠭ (Монгол бичиг, Mongol Bichig):

[Mongol_bichig.txt (text/plain, inline)]

 ᠮᠣᠩᠭᠣᠯ ᠪᠢᠴᠢᠭ

[Message part 3 (text/plain, inline)]

Emacs renders as follows:

[Message part 5 (text/plain, inline)]

The letters take different shapes (but same Unicode) based its
location in the word. For example, letter A in takes various forms:
- first form (isolate) 
- first form (initial)
- first form (medial)
- first form (medial)
But all takes same Unicode (U+1820) take a look at page 7 (upper left
part in page-7) in this manual. https://www.unicode.org/reports/tr54/

I think that Emacs is rendering only first form/variation of each letter
, and not changing it accordingly based on the its location.

------------------------------------------------------------------------

I know that number of people who use this Traditional Mongolian Scripts
in Emacs are basically none. But I'd be happy if Emacs renders it
correctly while other programs (such as vscode) already does.
