This is the CSS WG's response to an issue you raised on the last CSS
2.1 draft (http://www.w3.org/TR/2003/WD-CSS21-20030915). We want to
publish CSS 2.1 as a CR in about two weeks. Please let us know this
week if you think our response is wrong.

    15.2 Font matching algorithm

    I think the specification is too detailed here. When the page
    isn't displayed with the font the author primarily wanted, do this
    specifics of the font matching really matter? For example, on Mac
    OS X ATSUI already implements a font matching algorithm which
    could be considered good enough. Having to implement another
    matching algorithm on the application level is a performance
    problem. Consideration implementation difficulty, performance and
    the user experience, I think passing the list of font alternatives
    to the system Unicode imaging service and letting the system apply
    its fallback algorithm would be quite sufficient when the system
    offers font list-based fallback functionality. Also, considering
    user experience, allowing (but not requiring) the user agent to
    make decisions based on the content of the entire page is likely
    to be better than doing per character font selection.

CSS WG response:
    No change.
