Done all except Sinhala. It doesn't seem to have its own digits, apart from 
sets of archaic digits that were only just introduced into unicode.
Do you know if it uses digits from any of the other scripts now or just ASCII?

You are right regarding Sinhala. It seems to be using only the ASCII digits 
currently.

Even though a set of digits were defined as part of 
http://www.unicode.org/charts/PDF/U0D80.pdf they do NOT seem to be used. 
http://www.unicode.org/charts/PDF/U111E0.pdf have been defined in Unicode7 but 
no font support yet.

This seems to be fixed in the langdata repo in github, except for Sinhala. If 
there's still an issue, please file it on github. (Also, as I've synced with 
your version of the langdata repo, if you mention which branch to look at, I'll 
merge it into a pull request)
