I sometimes use the list at http://www.wazu.jp/gallery/Fonts_IPA.html to look up fonts.
IIRC (and I might not), Calibri, Meiryo, and Tahoma(Windows Vista or later) should have at least partial support of IPA characters. My fallback font is Lucida Sans Unicode. As for Heuristica, it's possible that the characters aren't incorporated into the built files (it's still a work in progress). You can file a ticket with the developers at their google code site. -Andy -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
