I use Bengali extensively in CC, and it's frustrating that the interface doesn't understand Bengali numerals as their latin equivalents - for example if I type ৩৩ in the font size, it doesn't understand it as 33. However, I noticed that in the latest version of InDesign (13.0 x64) it does recognize & convert Bengali numerals - for example when I type ৩৩ in the font size box it converts it to 33pt. However, this still doesn't work in the current version of Illustrator (22.0.1 x64), and it would make sense to have this feature throughout the major CC products.
