Hi, I am using the Vim module to typeset code, and I've found a situation where I'd like to use some math symbols, but not in comments. I am not sure whether it can be done. This is what I have tried:

\usemodule[vim] \definefontfamily [slidesfont][mono][Latin Modern Mono Light] \definefallbackfamily[slidesfont][mono][Xits][range={"0222A}] \definevimtyping[pascal][syntax=pascal] \starttext \startpascal X := Y ∪ Z; \stoppascal \stoptext

The ∪ symbol does not appear in the output. Am I completely off-track?

use dejavu mono instead of lm mono

Thanks, that works. Unfortunately, DejaVu Sans Mono looks too heavy in my document: is there a light variant? Also, can't the fallback mechanism be used? Nicola

Also, can't the fallback mechanism be used? Yes it can but you have to enable your custom typeface with \setupbodyfont which wasn’t done in your example.

You're right, but I have done it in my original document. Even with that, the fallback symbol does not show up: \usemodule[vim] \definefontfamily [slidesfont][mono][Latin Modern Mono Light] \definefallbackfamily[slidesfont][mono][DejaVu Sans Mono][range={"0222A}] \definevimtyping[pascal][syntax=pascal] \setupbodyfont[slidesfont] \starttext \startpascal X := Y ∪ Z; \stoppascal \stoptext Nicola

You have to move the fallback setting before the font where you want to apply the fallback, i.e.

    \definefallbackfamily […] […] […]     \definefontfamily     […] […] […]

Great, it works! Thanks to ConTeXt and this mailing list, I've cut down the time to prepare a presentation dramatically, while improving its quality and avoiding frustration (compared to LaTeX Beamer+listings). Nicola
