Greetings,
I have been trying to make font feature sets that allow me to write abbreviations in small caps and corporate entity/product/etc names with small caps replacing regular ones. I have run into an issue where c2sc works as intended on some fonts and not in others. No idea what that's about. MWE:
%\definefontfeature [default] [default] [script=latin] \definefontfeature [default] [default] [script=cyrillic] \definefontfeature [capstosc] [c2sc=yes] \definefontfeature [smallcaps] [cpsp=yes, smcp=yes, lowercasing=yes]
\setupbodyfont[stix] %\setupbodyfont[newcomputermodern-book]
\starttext
{\language[ru]Моя любимая {\feature[+][smallcaps]ОС}---{\feature[+][capstosc]Линукс}.}\crlf {\language[en]My favourite {\feature[+][smallcaps]OS} is {\feature[+][capstosc]Linux}.}
\stoptext
With STIX Two, c2sc (and smcp) works with any language as long as one doesn't select a script in the font features, else it only works with the chosen script. With New Computer Modern, it just doesn't work with any latin text no matter the script chosen. That is, plain small caps work, caps to small caps don't. What could be the reason to it? Is there anything I could do to mitigate it?
