Actually it is an alternate, but only partially. > > > \definefont > > [SomeFont] > > [name:iosevka*default:test] > > \starttext > > \SomeFont > > I live in a dot-heavy world. > > \stoptext > > > > has six dots instead of one dot over each "i".

In this font it's problematic though because the cv.. features have multiple loopup tables, one of which is a "multiple" lookup (used to decompose characters before applying the replacements, especially decomposing i into the stem and the dot) and another one is an "alternate" lookup providing multiple character variants. So selecting one of the other alternates requires that a number is passed, but passing the number enables the repetition in the multiple lookup... > > i can make that a 'context only' feature if needed That would certainly solve the issue for me, but it might be nice to provide a solution for context users too. Maybe the feature could be adapted to only interpret the argument as a replication factor if the "multiple" is the only lookup for the feature or if no other lookup for the feature is an alternate lookup?
