I am not regex nor CJK guru, but i afraid that in 1997 nobody care about
Unicode ;-) From my notes:

Japan:

    [\u3040-\u30ff]
    [\p{Han}\p{Hiragana}\p{Katakana}]

Chinese:

    [\u4e00-\u9FFF]
    \p{Han}

Korean:

    [\uac00-\ud7a3]
    \p{Hangul}

Arabic:

    [\u0621-\u064A]
    \p{Arabic}
