Hi, I'm continuing my quest for supporting Minion Pro font in my document. I defined the different sizes, as shown on contextgarden. But apparently, it does not (fully) work. The problems are : - When using \tfxx, \tfx, ... Regular font is always used, there is no switch to appropriate font. - When using \switchtobodyfont, switches are correct up to 12pt. After that, it fallback on xits-mathbold Any help is welcome :-) The compiled file : https://drive.google.com/file/d/0Bwo7pPA5_WkDdlNLbHdkMjg2dkU/view?usp=sharin...
