Hi Werner et al, I've given Emmentaler an OpenType lookup subtable for stylistic alternates, as the SMuFL specification suggests, and, as an experiment, I have successfully encoded the two types of double whole note (breve), one as a stylistic alternate of the other. However, LilyPond's current library for reading music fonts, FreeType, doesn't seem to support OpenType layout tables.
SMuFL's specification doesn't require a program to support OpenType features. It states that a compliant font should also have some metadata JSON files that describe the same stylistic alternate and ligature information for such a program to read. That said, it looks like I could go two ways. Would you rather I switch FreeType for a font library with OpenType layout table support, or keep FreeType and have LilyPond take what it needs from a SMuFL font's metadata files? (And of course, I might have missed something, so please let me know if I did.) Thanks, Owen
