sentenceDifficulty関数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
The sentence's score, lowest first: its length in characters plus three times its hardest kanji.
Kana-only sentences score their length alone, which puts them at the top where they belong: a
beginner can read every one of them. A kanji missing from costs counts as the hardest kind.
