This study by Open Institute, funded by Development Innovations and The Asia Foundation, examines Cambodian phone users’ knowledge, attitudes and practices in relation to Khmer-language typing, writing and search habits, and identifies the factors motivating them to use (or not use) Khmer script. It also attempts to identify changes and trends in the way Khmer-enabled phones are being used, including their role as a means of accessing the Internet – in particular, Facebook, the most popular social media site in Cambodia with over 3.4 million users as of December 2015, a 22% penetration rate.
