Restrict input to Arabic characters

I attempted to enforce the requirement for users to input Arabic characters in the “Arabic first name” field by adding the constraint “regex(.,‘[1]’)”. While this constraint functioned correctly when entering data via the form link, it encountered an issue when used through the KoboCollect application on a tablet. Specifically, it displayed an error message stating, “Sorry, this response is invalid!” upon input. Could you please provide advice on resolving this issue?
