Please include an option to pick from the installed %windows%/fonts/ folder when picking a font type to display scripts and tooltips in.
or at very least, include the GNU unifont font in your list of options http://unifoundry.com/unifont.html
I would personally like to pick my installed "Arial Unicode MS" font.
but the non-proprietary GNU unifont would be acceptable.
