CJK
<character> In
internationalisation, a collective term for Chinese, Japanese, and Korean.
These languages all share the fact that their writing systems are based partly on Han characters (i.e., "hanzi" or "
kanji"), which are complex enough of a system to require 16-bit character encodings.
CJK character encodings should consist minimally of Han characters plus language-specific phonetic scripts such as pinyin, bopomofo, hiragana, hangul, etc.
CJKV is CJK plus
Vietnamese.
