Hi, I'm pretty new to ConTeXt, so please bear with me if the following has already been asked (I have not found any answer in the archives, though). My goal is to use an arbitrary text font together with the Euler math font. I am able to use a few combinations in ConTeXt, e.g. Palatino with Euler, without problems. But when I switch to XeConTeXt (to use my system's fonts), some Euler's math accents do not show up properly (\hat) or not at all (\acute, \grave, \bar, \breve, \dot, \ddot, \tilde, \check). I guess the problem is the different encoding (and possibly the use of virtual fonts), but I know that Euler works in XeTeX: is it possible to make it work in XeConTeXt? Below you find my sample code.
