    OK for the "numeric" versus "capitalize|uppercase|lowercase" remark, which
    is related to form validation and has probably nothing to do within the
    Unicode list. But the general discussion of the behavior of BiDi with
    vertical scripts, or horizontal scripts rendered vertically (or even in
    Boustrophedon) is still something that the Bidi algorithm in Unicode is not
    solving completely. There are bidirectional properties that are inherent to
    scripts and their characters, and that are in the direct focus of Unicode

    Although this was discussed in relation with CSS3, this is still a big issue
    of Unicode because it's not a problem specific to CSS as it directly affects
    any rendering of plain text.

    The CSS3 article was very interesting to read because it really speaks about
    problems that exist today with scripts already in Unicode, and for which the
    BiDi properties do not seem enough to effectively write a generic renderer
    for all of them (including the interation of Latin/Greek/Cyrillic with
    Han/Hiragana/Katakana, or the special interaction of Hiragana/Katakana in
    Han text.)

    I bet that if the proposed CSS3 model works, it will demonstrate which
    properties need to be added by Unicode in its standard, for use in other
    non-CSS based applications. May be this will require now BiDi controls and a
    more complex algorithm to handle them. For now, the only "safe" way to do
    that is to base the augmented properties on the "script" property of
    characters (but still with ambiguity problems for general purpose characters
    like punctuation and spacing).
