Hi, is there an already existing option to reduce umlauts etc. to ascii counterparts, e.g.     \starttext     Füße     \stoptext results in     Fusse The fonts manual gives an example for a font feature with the desired output but it's possible I missed something or there is a better solution. \startluacode local shapedcodes = { } for k, v in next, characters.data do     local s = v.shcode     if s then         if type(s) == "number" then             shapedcodes[utf.char(k)] = { utf.char(s) }         elseif #s == 2 then             shapedcodes[utf.char(k)] = { utf.char(s[1]), utf.char(s[2]) }         end     end end fonts.handlers.otf.addfeature {     name = "simplify",     type = "multiple",     data = shapedcodes, } \stopluacode \definefontfeature [simplify] [simplify=yes] \starttext Füße \feature[+][simplify]Füße \stoptext Wolfgang
