Sorry if this isn't exactly the most 'language' related question, but what ranges of Unicode code points are needed to write Japanese?
I've got the Hiragana, Katakana, punctuation, etc; but the jōyō-Kanji are mixed in with the other Chinese characters.
I'm not asking for each code point, just the ranges, the pairings of starting and ending code points needed to define blocks of kanji.
