A group of linguists in Korea are looking into giving people with no written form of their language ways to write using the Korean alphabet (hangŭl), according to this article.
A number of communities they visited in Indonesia were keen on using hangŭl to write their languages and plan to send representatives to Korean to learn the alphabet, who will then to teach it to their communities.
The Korean alphabet is currently used only to write Korean, so it will be interesting to see how well it will work for other languages.
