Hi,
Jean-Pierre Le Narzul
Any idea ?
Yes: don't use computer-modern fonts. They don't have { } and _ except for typewriter. Use any other font encoded in ec or texnansi or whatever encoding. See for example latin-modern: ================================================== \starttext \setuptyping[typing][color=black,style=\ss,escape=/,option=commands] \starttyping hello_world {brace} \stoptyping \setupencoding [default=ec] \usetypescript [all] [latin-modern] [\defaultencoding]% \setupbodyfont[reset]% \setupbodyfont[cmr]% \starttyping hello_world {brace} \stoptyping \stoptext ================================================== Patrick PS: and please (!!!) provide a minimal but complete working (or no-working) example next time. It would save the others some time. -- Silent is the goldfish in its bowl
