Issue

U+0F0E TIBETAN MARK NYIS SHAD is slightly narrower than two adjacent U+0F0D TIBETAN MARK SHADs, but The Unicode Standard says that U+0F0E should be wider, or at least not narrower. However, many Tibetan fonts, including some made by people who know Tibetan, do make U+0F0E narrower. It is not clear what to do, but as long as you’re redesigning Noto Sans Tibetan, you should be aware of the issue.

@dscorbett : my reading of what's coming in Unicode that this is a designer choice (and Unicode will be changed) hence I'm closing this one

@dscorbett : Looks that for some Tibetan fonts which came from China's Tibetan Research Center the following are the same (so we might need to further revise Unicode spec): U+0F0E TIBETAN MARK NYIS SHAD two adjacent U+0F0D TIBETAN MARK SHADs single U+0F0D TIBETAN MARK SHAD

My gut feeling is that there shouldn't be a spec regarding the distance between SHADs
