Dear list, I have the following sample (using current latest from 2022.12.01 13:05): \definefallbackfamily[mainface][rm][Noto Emoji] [range={0x1F004-0xFE837}, force=yes] \definefontfamily[mainface][rm][TeX Gyre Pagella] \setupbodyfont[mainface] \definestructureconversionset [sectionnumbers] [0,n,Characters,g,n] [n] \definefontfeature[section] [smcp=yes, c2sc=yes] \setupheads[sectionconversionset=sectionnumbers] \setuphead[section][style={\feature[+][section]}] \starttext \section{Just text} {\feature[+][section]Just text} \stoptext LMTX outputs no small caps and it fallbacks to Noto Emoji. LuaTeX gives the right output. Am I missing something or have I hit a bug in LMTX? Many thanks for your help, Pablo
