Hi, I know this won't ever make it to Obsidian core, but seems perfect for a plug-in:
Support for displaying numbers as Eastern-Arabic numerals (٠, ١, ٢, ٣, ٤, ٥, ٦, ٧, ٨, ٩). Microsoft word has this feature, where the user can type 3 but depending on his settings it will be displayed as ٣. This is great to make the content appear cohesive and uniform, while also preserving inter-operability.
Would there be any interest in developing this feature? Or if not, I'm a total beginner to Obsidian plug-ins but could give it a shot with your advice (whether it's feasible and what approach I should take). Thank you!
