Dear list, I have the following sample: \mainlanguage[agr] \setuppapersize[A5] \definefallbackfamily [mainface] [rm] [GFS Didot] [preset=range:greek, force=yes] \definefontfamily [mainface] [rm] [TeX Gyre Pagella] \setupbodyfont[mainface] \starttext \setinitial Πρῶτον δεῖ θέσθαι τί ὄνομα καὶ τί ῥῆμα, ἔπειτα τί ἐστιν ἀπόφασις καὶ κατάφασις καὶ ἀπόφανσις καὶ λόγος. \blank\setinitial Ὄνομα μὲν οὖν ἐστὶ φωνὴ σημαντικὴ κατὰ συνθήκην ἄνευ χρόνου, ἧς μηδὲν μέρος ἐστὶ σημαντικὸν κεχωρισμένον· \stoptext When the initial is a character from the extended Greek Unicode block, the fallback family doesn’t work for that initial. Could anyone confirm that this is a bug? Many thanks for your help, Pablo -- http://www.ousia.tk
