Hello, compiling the following with 'context'
\starttext \startformula J:\blackboard{R}^\infty \rightarrow \blackboard{R},f \mapsto J[f] \stopformula \stoptext produces a blackboard 'J' character in J[f] instead of a $J$. The log file contains: system > beware: some patches loaded from cont-new.mkiv fonts > latin modern fonts are not preloaded fonts > latin modern fonts are not preloaded fonts > virtual math > unable to resolve name mapsfromchar fonts > fallback modern rm 12pt is loaded mkiv lua stats > luatex banner - this is luatex, version beta-0.70.1-2011052008 if this is of any help.
