Dear List, I'm using the last update of ConTeXt Standalone, ConTeXt Process Management 0.63 - current version: 2016.06.25, on Windows 10. All the fonts are installed (Theano Didot, ipaexmincho, GaramondNo8 and FreeSans, usw) and there seems to be a conflict between French and Ancient Greek. See logfile as attached piece. I've got a conflict and a fatal error in the logfile (but a 'q' command allows to overpass the alert) in line 2 of this code : \setuplanguage[fr][patterns={fr,agr}] \mainlanguage[fr] \setuplayout [backspace=40mm] \setuppagenumbering[alternative=doublesided, location={header, inmargin}] \setupmargindata[inmargin][location=inner, style={\ssx\setupinterlinespace[line=2.8ex]}] \setupmarginframed[inmargin][align=right] \setupbodyfontenvironment[default][em=italic] \definefallbackfamily[mainface][serif][Theano Didot][preset=range:greek, it={Old Standard Italic}, force=yes] \definefallbackfamily [mainface] [rm] [ipaexmincho] [range=cjkunifiedideographs] \definefontfamily [mainface] [serif] [GaramondNo8][sc=NewG8 Regular SC] \definefontfamily [mainface] [sans] [FreeSans] [rscale=0.7] \setupbodyfont[mainface] \setupindenting[1.5em] \setupindenting[yes] \setupwhitespace[medium] \setupinterlinespace[line=3.2ex] \setupitemize[each][margin=yes] \setuphead[title][header=empty] \setupheader[style={\sc}] \setupfooter[style={\itxx}] \setupheadertexts[Cours de Philosophie][][][{\getmarking[section]}] \setupfootertexts[][][][© J.-P.
