Small editorial comments: Btw, I also think you should change "in a given natural language, such as English or Japanese Hiragana." to read "in a given natural language, such as English or Japanese (written here in hiragana)." (The language of ja-hira is still just Japanese, even though the tag also indicates that it is written using hiragana.) Also, very minor nit, I don't think you need to titlecase Kanji, Hiragana, etc in 5.6.5.
