Even Computer Modern!
Do you mean to tell me that the TeX Gyre fonts are all "broken"?
And that the *only* correctly working font is ... Cambria?
So following up on the font discussion at the last ConTeXt meeting,
must we conclude that *all* of the fonts that we distribute with the
Standalone are to be avoided, and that one must pilfer the MicroSoft
font in order to typeset mathematics correctly?
