Mostly. there are some edge cases where one works and the other gives an error compare on this for example https://github.com/davidcarlisle/utex/blob/master/testfiles/udelcode-002.lvt But I think in all cases where they both give a reasonable result, the result is the same. (I think I've reported all the things shown up by the tests in https://github.com/davidcarlisle/utex/ to one engine tracker all the other although I haven't checked recently) David
