    I am not sure of you main point here - I was refering to how the IDS
    are rendered as in Unicode 5 page 430 where it says;-

    'An implementation may render a valid Ideographic Description Sequence
    either by rendering the individual characters separately or by parsing
    the Ideographic Description Sequence and drawing the ideograph so
    described. In the latter case, the Ideographic Description Sequence
    should be treated as a ligature of the individual characters for
    purposes of hit testing, cursor movement, and other user interface

    To use IDS in running Zhuang text and "parse" is acceptable, and in a
    text containing a large number of IDS sequences even desirable from
    the point of view of human readbility.

    Yours sincerely
    John Knnightley
