Hello,

This might be interesting.

I do remember a year or so ago, we had a discussion on this mailing list or on Wikimedia-l (I tried to find the thread, but failed) where we found any template where a calculation is needed, Indian-language numbers or digits are not working. A general conclusion was citing an RFC which states Indian-language numbers/digits are considered as letters.

User:আফতাবুজ্জামান (User:Aftabuzzaman) showed a template https://bn.wikipedia.org/s/a7tz which is supported by a module https://bn.wikipedia.org/s/9utr which converts the Indic-language numbers, hence allows the calculation to be done in Indic-language digit itself.

Perhaps some of you will find it useful
