I saw this. But it comes from the UprightFont option. So I'm asking again: why don't you drop it? Fontspec obviously don't expect that the value of this key has an extension. > So its a bug. Perhaps. \setmainfont[UprightFont=arial.ttf]{arial.ttf} worked in TL15 but not in TL16. But as I don't see the reason for this setting I don't know if it a bug or if simply some unsupported side-effect no longer works. But you should better ask this in the issue tracker of fontspec: https://github.com/wspr/fontspec/issues -- Ulrike Fischer http://www.troubleshooting-tex.de/ -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
