Dear Ashraf Zaher,
Thank you for contacting us.
Indeed, the left to right languages are only supported in our "Core" technology. These are not supported in our iink SDK nor in our Nebo application. At present, we cannot commit if/when this will be done.
At present, the Arabic language is not supported by the iink SDK.
Is it possible to learn more about your use-case? Do you want to develop an application with interactivity?
