Hello list, i'm trying to add a smallcaps variant to the MyriadPro font, since it does not implement the smcp opentype feature. My strategy: - "transplant" the uppercase letters of the MyriadPro-Regular into the lowercase letters of the same font with a font fallback that scales down the glyphs ("FakeSansCaps" in the following source) - since the scaled down glyphs get also thinner traits, embolden them with a font feature effect ("emboldened" in the following source) to make them consistent with the "real" uppercase letters What is not working: i don't know how to map the uppercase letters to the lowercase range; i tried to specify an offset of -32 in \definefontfallback[FakeSansCaps][SansEmboldened][0x61-0x7a][rscale=.8,force=yes,offset=-32] but it does not work. Here's the minimal (not) working example: \starttypescriptcollection [myriadpro] \definefontfeature[emboldened][effect={width=0.1,delta=0.4,factor=0.3}] \starttypescript [sans] [myriadpro] \definefontsynonym [Sans] [file:MyriadPro-Regular.otf] [features=default] \definefontsynonym [SansItalic] [file:MyriadPro-It.otf] [features=default] \definefontsynonym [SansBold] [file:MyriadPro-Bold.otf] [features=default] \definefontsynonym [SansBoldItalic] [file:MyriadPro-BoldIt.otf] [features=default] \definefontsynonym [SansSlanted] [file:MyriadPro-It.otf] [features=default] \definefontsynonym [SansBoldSlanted] [file:MyriadPro-BoldIt.otf] [features=default] \definefontsynonym [SansEmboldened] [Sans] [features=emboldened] \definefontfallback[FakeSansCaps] [SansEmboldened] [0x61-0x7a] [rscale=.8,force=yes] % offset? \definefontsynonym [SansCaps] [file:MyriadPro-Regular.otf] [fallbacks=FakeSansCaps] \stoptypescript \starttypescript [myriadpro] \definetypeface [myriadpro] [ss] [sans] [myriadpro] [default] \stoptypescript \stoptypescriptcollection \usetypescript[myriadpro] \setupbodyfont[myriadpro,ss] \starttext % scaled up 4 times to appreciate the thickness compensation \scale[sx=4,sy=4]{\sc SoMe CaMeLcAsE TeXt.}\par \stoptext
