Changing « Preferred Family » value

Hi ! I've just been assigned a bug report on a font package I maintain in Fedora [1]. I'm not very familiar with fonts (I took over this package as it was orphaned and needed by the fedora-olpc effort), so I don't really know how I should proceed to fix it. Is there a way for me to patch the TTF file ? Does this belong upstream, so I should report it to the font developer ? Any hint would be greatly appreciated.
