Well imho it is a difference if a font set this values and xetex simply reads them in or if the font doesn't set this values and xetex guesses (faulty) defaults. Actually I found an old discussion which seems to imply that xetex calculates the fontdimens starting from the width a space -- and doesn't care about monospace or not: https://tug.org/pipermail/xetex/2006-June/004236.html -- Ulrike Fischer http://www.troubleshooting-tex.de/ -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
