Subject: Adjust Mongolian shaping
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=22a685836a59d1c02914761c02d3852810b83ec5;p=platform%2Fupstream%2FlibHarfBuzzSharp.git

Adjust Mongolian shaping

For U+1880..U+1886 Uniscribe thinks they are non-joining.
For U+1887 Uniscribe thinks it's joining, but looks wrong to me.
For now, match Uniscribe.
