I have been using TUG's Lucida Type1 fonts for a while in ConTeXt, but
a recent update of the standalone version of ConTeXt is giving the
following when building a document containing math:
unknown math characters: μ (U+003BC) σ (U+003C3) χ (U+003C7) (n=44)
Obviously, it's having a problem with \mu and \chi, and these
characters are showing up as a "?" in the document.
Does anyone know what may have changed recently to break Lucida Type1 support?
