The Free On-line Dictionary of Computing (30 December 2018):

CJK

    In internationalisation, a collective term for
   Chinese, Japanese, and Korean.

   The characters of these languages are all partly based on Han
   characters (i.e., "hanzi" or "kanji"), which 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.
