In 2009, a group of Wolio speakers known as the Cia-Cia adopted the Korean script, hangul, to write their language. They had previously not had a formal means of transcribing their language. The move was supported by the Hunminjeongeum Research Institute in Seoul, which had tried to interest a number of previously illiterate Asian societies in using Hangul. The Cia-Cia initiative was their first success. The language claims about 80,000 speakers.
