20% beware, base mode + dynamics can give weird effects

52%D \starttyping
53%D \ruledhbox{\char"2012}\par % figuredash
54%D \ruledhbox{0}\par
55%D \stoptyping
56
57%D We wipe math from text fonts, just to be sure, but in some cases like koeieletters and
58%D euler we can't do that, so there we have to disable it (in the typescript).

924%D   {tinyfont}
925%D
926%D By default we load the Computer Modern Roman fonts (but not yet at this moment)
927%D and activate the 12pt roman bodyfont. Sans serif and teletype are also available
928%D and can be called for by \type {\ss} and \type {\tt}. Loading takes place
929%D elsewhere. For tracing purposes we define:
930
931\definefont[tinyfont][file:dejavusansmono at 1ex]
932
933%D \macros
934%D   {infofont}
935%D
936%D The second situation occurs when we enable the info mode, and put all kind of
937%D status information in the margin. We don't want huge switches to the main
938%D bodyfont and style, so here too we use a direct method.

949%D Optimization (later we overload in math). Also needed in order to get \type {\ss}
950%D properly defined.
