    There is no need to change ::drawChars(). Just add <int>0xfeff</int> to
    the <blank>...</blank> item in /etc/fonts/fonts.conf

    It should be there in recent versions of fontconfig.

    Btw, Tomas, why are you using 0xfeff to express something about
    ligatures? Is there no way to express it using the unicode zero-width
    joiners? What's exactly the role that it plays? To force an optional
    ligature?

    Cheers,
