I have posted a short list of some basic kanji sorted by their UCS code over at http://kanjirecog.blogspot.ca/2012/10/kanji-by-ucs.html.
That list is only
一 丁 七 万 丈 三 上 下 不 与 世 丘 丙 両 並 中 丸 丹 主 久 乏 乗 乙 九 乱 乳 乾 事 二 亜 享 京 亭 人 仁 今
I will try to find a moment to put a complete view of the jōyō kanji sorted on that basis.
Feedback most welcome.
Several of my pages at http://kanji.aule-browser.com display the UCS or UTF-16 hex value - and I have a little utility ready to flip between kanji, code and the web urlencoded utf-8 version for URL's.
cheers
Robert
