2012/8/2 Peter Dyballa <Peter_Dyballa at web.de>: > XeTeX has been patched to enable micro-typography in TeX Live 2009. To make use of it you need the microtype package v2.5, beta (microtype-xetex.def). This came with TeX Live 2010. AFAIK only protusion. I doubt that expansion is possible with XeTeX. Best Martin
