Beyond ASCII, you almost automatically loss. For example, in ISO8859-1 context, uppercase of 'y' with diaeresis is not 'Y' with diaeresis, because there is no 'Y' with diaeresis in ISO8859-1, which is bad enough. So, I can understand your attempt to insist on lowercase, but it does not work because DNS does not allow it. Masataka Ohta
