device name encoding error, when it send to email.

There is an error in the device name encoding.
The error occurs when the system sends notifications email.

Device name like:
teltonika-الشركة العربية/60

It appears in the title of the message as follows:
teltonika-?????? ?????-? ? ? ? ?/60

It is likely that the encoding is incorrect.

My question is what part of the code can I fix?

Does it display name correctly in the web app?

yes

I see. Could be some limitation in the templates formatting. You can probably debug NotificationFormatter class to see what's happening.

ok thanks
