[NTG-context] Fontawesome in lmtx

Hi, if there any changes in the interface for using symbols? I tried today the example from Aditya's Blog but it shows no symbols: \definetypeface[mainfont][rm][specserif][Linux Libertine O][default] \definetypeface[mainfont][mm][math] [TeX Gyre Pagella Math][default] \definetypeface[mainfont][tt][mono] [Dejavu Mono][default] [rscale=0.8, features=none] \setupbodyfont[mainfont,11pt] \usesymbols[fontawesome] \define\FA{\dosingleargument\doFA} \def\doFA[#1]{\inlinedbox {\scale[height=1em]{\symbol[fontawesome][#1]}}} \starttext Checked box \FA[check-square-o] Unchecked box \FA[square-o] \stoptext i use luamtetex for archlinux with all luatex modules linked to lmtx folder -- Dr YAHYAOUI Mohamed Kaddour, cardiologue .
