    Hello,

    Is there a way within a JavaScript program to enumerate
    all of the available fonts on a system and then to check
    them for support for a particular Unicode character? I
    need to find a font that can draw the cube root symbol
    U+221B for my web calculator when the new html canvas tag
    is not supported (such as on Internet Explorer).

    Thanks,

    Mike

    P.S. see http://mikestoolbox.com/calc-help.html if you are
    interested in the calculator
