How to check if users submit Arabic words from a form?

Question

Is there any reliable way to check if a user has entered Arabic words in a form and is trying to submit it? Can Javascript handle this? Or can only a script server, such as .NET, do this?

I think that if possible, the script should explicitly prevent the user from entering Arabic words in the form and show a pop-up warning.

Please share any examples if you have ideas on how to do this.
