Tifinagh script is used for one of the Berber languages. It is the original script for these languages and it is there to be used. Using it is hard when your computer does not support it.
The Narayam extension does allow the use of input methods on top of an international keyboard. When the Tifinagh script is to be supported, it helps when an organisation is putting its weight behind a particular input method. For the Tifinagh script it is the Royal Institute for the Amazight culture; they defined a keyboard, they provide a manual on how to use it and we are happy to support this keyboard in Narayam.
The Royal Institute produced many beautiful fonts; it would be nice when we find that we can use these as well and truly promote the use of the Amazight culture worldwide.
