Hi Hans, the mapping for the SmallCaps fonts from Latin Modern use the slanted version for upright and the upright version for slanted style. font-otf.tex: \definefontsynonym [LMRoman10-CapsRegular] [file:lmromancaps10-oblique] [features=default] % features=smallcaps? \definefontsynonym [LMRoman10-CapsOblique] [file:lmromancaps10-regular] [features=default] should be \definefontsynonym [LMRoman10-CapsRegular] [file:lmromancaps10-regular] [features=default] \definefontsynonym [LMRoman10-CapsOblique] [file:lmromancaps10-oblique] [features=default] The mapping for the Dunhill style seems to be wrong too. \definefontsynonym [LMRoman10-Dunhill] [file:lmromandunh10-oblique] [features=default] \definefontsynonym [LMRoman10-DunhillOblique] [file:lmromandunh10-regular] [features=default] Wolfgang
