(but I don't see why locale should be different when a program is run from inside context then when it is run from a shell).
Taco can surely better explain why. I think somewhere in the luatex manual, he explains why luatex sets locale to "C". To see the differences in the environment, just do "set >/tmp/set-shell" and run context on: --8<---------------cut here---------------start------------->8--- \starttext \ctxlua{os.execute"set >/tmp/set-context"} \stoptext --8<---------------cut here---------------end--------------->8--- I don't have pandoc, but I'm sure that you can reproduce the problem with "LANG=C pandoc ..." Thus, the solution would be something like: "filtercommand={LANG=en_GB.utf8 pandoc ...}" -- Peter
