You cannot convert uppercase string in Unicode to lowercase (or vice versa) without knowing about all collation rules in all possible languages. (And, yes, precisely because of that your paranoid resolver won't be able to compare results of a reverse DNS lookup with what A records say - even if you don't plan to use domain names with Devanagari in it, people from these domains may visit your server). Having to install tons of locale configurations just to get name resolver to work does not strike me as a good idea. --vadim PS Unicode is broken-as-designed - it requires rich text format to do elementary things like lexicographic sorting or case-insensitive comparisons. If you do have RTF with language tags of some kind, Unicode is redundant. |
