Registration problem on RTL direction

Hi,

I’ve changed the theme direction to RTL in Farsi language.
On some mobile devices when a user wants to register and type email, it gives an error that the email is not valid. For example if the email is “example123@email.com” it becomes something like “@email123example.com”.
However, when I check the users in admin area, I can see that user is registered but user have no idea and thinks that registration is unsuccessful.
The solution is to change numbers from Farsi to English. So how can I keep the website direction in RTL and at the same time, change numbers from Farsi to English? Or at least change numbers to English only at the registration form fields?

Thank you,
