I can't get create a font fallback in the the example below, so some input is welcome. It works when using STIX2 only (the commented out part), but somehow the font name is not recognized in the fallback, not when using what is listed by 'mtxrun --script fonts --list --all'. β \definefontfamily[stix-two][mono][Stix Two Text] \definefontfamily[stix-two][math][Stix Two Math] %\setupbodyfont[stix-two,10pt] \definefallbackfamily [mainface] [rm] [Stix Two Text] [range={02070,0208F}] \definefallbackfamily [mainface] [serif] [Stix Two Text] [range={02070,0208F}] \definefallbackfamily [mainface] [mono] [Stix Two Text] [range={02070,0208F}] \definefallbackfamily [mainface] [math] [Stix Two Math] [range={02070,0208F}] \definefontfamily [mainface] [rm] [stix] \definefontfamily [mainface] [math] [stix] \definefontfamily [mainface] [mono] [stix] \setupbodyfont [mainface] \starttext \startformula \startalign \NC π¨β 0 β 1 β 2 β 3 β 4 β 5 β 6 β 7 β 8 β 9 β + β - β = β ( β )\NR \NC π©β° 0 ΒΉ 1 Β² 2 Β³ 3 β΄ 4 β΅ 5 βΆ 6 β· 7 βΈ 8 βΉ 9 βΊ + β» - βΌ = β½ ( βΎ )\NR \stopalign \stopformula \starttyping π¨β 0 β 1 β 2 β 3 β 4 β 5 β 6 β 7 β 8 β 9 β + β - β = β ( β ) π©β° 0 ΒΉ 1 Β² 2 Β³ 3 β΄ 4 β΅ 5 βΆ 6 β· 7 βΈ 8 βΉ 9 βΊ + β» - βΌ = β½ ( βΎ ) \stoptyping π¨β 0 β 1 β 2 β 3 β 4 β 5 β 6 β 7 β 8 β 9 β + β - β = β ( β ) π©β° 0 ΒΉ 1 Β² 2 Β³ 3 β΄ 4 β΅ 5 βΆ 6 β· 7 βΈ 8 βΉ 9 βΊ + β» - βΌ = β½ ( βΎ ) \stoptext β
