Dear list, I have the following sample: \enableexperiments[fonts.compact] \definefallbackfamily [mainface][rm][Dejavu Sans] [sl={style:regular, features:slanted},preset=range:greek] \definefontfamily [mainface][rm][Latin Modern Sans] %[sl={style:regular, features:slanted}] \setupbodyfont [mainface] \starttext αβγ9 some word others\\ \sl αβγ9 some word others \stoptext The only way to get slanted Greek is either not to enable compact fonts or to add fake slanted to \definefontfamily. I’m experiencing this with LMTX only (MkIV is fine). I’m using current latest (2024.11.01 19:19). Could anyone confirm the issue? Many thanks for your help, Pablo
