Big5

Big-5 or Big5 (Chinese: 大五碼) is a Chinese character encoding method used in Taiwan, Hong Kong, and Macau for traditional Chinese characters. The People's Republic of China (PRC), which uses simplified Chinese characters, uses the GB 18030 character set instead (though it can also substitute Big-5 or UTF-8). Big5 gets its name from the consortium of five companies in Taiwan that developed it.
