    I'm not sure that's what he wants either. In dictionaries that give a Stroke
    Order index, strokes are usually sub-sorted by the stroke category of the first
    one or two strokes of the character. Whilst you can get this information from a
    sequence of all strokes, that is more than is needed.

    Coincidentally I've recently been in contact with someone who has spent the last
    ten years creating a database of CJK ideographs, similar in scope to the Unihan
    database, but (according to him) more systematic and accurate. His database does
    include ideographic decompositions (as well as stroke categorization of the
    first two strokes of each character). The main problem with ideographic
    decompositions is that not all discrete ideographic components are [currently]
    encoded within Unicode - there are about 100 unencoded ideographic components
    according to this person. Of course you could get around them by breaking them
    down directly into their component strokes, but this would be an inelegant


    P.S. If anyone is interested in cooperating with this person, please contact me
