Please add INR (Indian Rupee) symbol (₹) to the editor
That is an interesting one - I would log a call with support requesting this as the editor will have a config which may be locale to your instance and allow you to have this added.
Log an idea for this! You can certainly paste that character into your text, but we can also add this to the "insert symbol" dialog in the text editor.
Thanks Neil Robertson-Ravo and Justin Cooperman
