Dear list, I have the following sample: \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, profile={sRGB, default_gray.icc}, level=0] \setuptagging[state=start] \setupcolors[cmyk=no, pagecolormodel=auto] \definefontfamily[mainface][rm][TeX Gyre Heros] \definefontfamily[mainface][tt][Cousine] \setupbodyfont[mainface] \starttext \input zapf \tt\input zapf \stoptext I’m afraid that Acrobat isn’t able to display the fonts and SumatraPDF displays random characters with Cousine, when compiled with current latest (from 2021.04.26 00:55). Previous latest from 2021.04.21 11:39 has no probles with the fonts (either in Acrobat, or in SumatraPDF). Could anyone confirm this issue? Many thanks for your help, Pablo -- http://www.ousia.tk
