[NTG-context] UTF-8 characters and gnuplot module

Hi everyone, I'm currently learning how to use the gnuplot module (thank you Mojca, and all the others, for this great tool!). I stick for now with the metapost terminal, as I'm not sure I'd be able to recompile gnuplot in order to add the context terminal. It seems that accents are not supported in gnuplot scripts. In the example below, both the methods to typeset accents fail. Is there a solution to this? Maybe there is something wrong with my settings... Best regards, Morgan \usemodule[gnuplot] \setupGNUPLOT[terminal=mp] \startGNUPLOTscript[sin] set xlabel "héllo h\'ello" plot sin(x) \stopGNUPLOTscript \starttext \useGNUPLOTgraphic[sin] \stoptext
