Cambria Math (commercial) Asana Math XITS Neo Euler How theengine-only switch could recognize which fonts do you wish to use? Moreover \Omega in the math sense must be typeset in math italic while as a unit (Ohm) it must be upright and may be taken from any font containing Greek. It would be better to have a unicode SI units package that will allow users to select a font they like. > ? >> >> >> Regards, >> Bruno >> >> >> >> -------------------------------------------------- >> Subscriptions, Archive, and List information, etc.: >> http://tug.org/mailman/listinfo/xetex > > > > -------------------------------------------------- > Subscriptions, Archive, and List information, etc.: > http://tug.org/mailman/listinfo/xetex -- Zdeněk Wagner http://hroch486.icpf.cas.cz/wagner/ http://icebearsoft.euweb.cz -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
