Edit Question
Title
Body
Given a string in Ruby 1.8.7 (without the awesome Oniguruma regular expression engine that supports Unicode properties with \p{}), I would like to be able to determine if the string contains one or more Chinese, Japanese, or Korean characters; i.e. class String def contains_cjk? ... end end >> '日本語'.contains_cjk? => true >> '광고 프로그램'.contains_cjk? => true >> '艾弗森将退出篮坛'.contains_cjk? => true >> 'Watashi ha bakana gaijin desu.'.contains_cjk? => false I suspect that this will boil down to seeing if any of the characters in the string are in the Unihan CJKV Unicode blocks , but I figured it was worth asking if anyone knows of an existing solution in Ruby.
