I have added the feature to add suffix of non-arabic, indian numerals to the Page names for various indian languages.
Get the new zip from https://github.com/tshrinivasan/OCR4wikisource and use it.

Added indian numerals for bengali, odiya, gujarati, telugu, kannada, malayalam

Got the numbers from https://en.wikipedia.org/wiki/Indian_numerals

Is there any language wikisource uses indian numerals?

if so, share the number and symbols.

Thanks.
