No, I'm not sure at all. All I can say is that a quick check in my scholarly books didn't bring up a single example where uppercase and lowercase were treated differently. If I apply your code, I will have the same problem with Azygous -> aardvark. How would I write the table so that lowercase and uppercase are not distinguished at all? I tried \startluacode sorters.mappings['en'] = { ["a"] = 1, ["b"] = 2, ["c"] = 3, ["d"] = 4, ["e"] = 5, ["f"] = 6, ["g"] = 7, ["h"] = 8, ["i"] = 9, ["j"] = 10, ["k"] = 11, ["l"] = 12, ["m"] = 13, ["n"] = 14, ["o"] = 15, ["p"] = 16, ["q"] = 17, ["r"] = 18, ["s"] = 19, ["t"] = 20, ["u"] = 21, ["v"] = 22, ["w"] = 23, ["x"] = 24, ["y"] = 25, ["z"] = 26, } \stopluacode but that didn't work.
