I also reached out to them on Twitter but they directed me to this form. I followed up with them on Twitter with what happened in this screenshot but they are now ignoring me.

    Personally I don’t think that sucks or is even wrong. Case-independent text processing is more cumbersome. ‘U’ and ‘u’ are two different symbols. And you have to make such rules for every language a part of your processing logic.

    If people can take case-dependence for passwords (or official letters and their school papers), then it’s also fine for email addresses.

    The actual problem is cultural, coming from DOS and Windows where many things are case-independent. It’s an acquired taste.

      Unicode has standard rules for case folding, which includes the rules for all languages supported by Unicode. Case-insensitive comparisons in all good programming languages uses this data.

      Note that you can’t simply convert both strings to uppercase or lowercase to compare them, as then you’ll run into the Turkish i problem: https://haacked.com/archive/2012/07/05/turkish-i-problem-and-why-you-should-care.aspx/

        So good that we all use Unicode now. No CP1251, no ISO single-byte encodings, no Japanese encoding hell.

        It’s that capitalization is language dependent, which email addresses shouldn’t be as I hope the rules for France shouldn’t be different than for Dutch. For instance é in Dutch is capitalized as E, but in French it is É. The eszett didn’t even have an official capital before 2017

        In most programming languages, case-insensitive string compare without specifying the culture became deprecated. It should imo only be used for fuzzy searching doubles, which you probably will do with ToUpper on all four performance reasons, or maybe some UI validation.

          Sure, but we’re just talking about string comparison rules, and Unicode sees all three of those as being equal. For example, a search engine that uses proper case folding rules in its indexer should return results for “entrée” if you search for “entree”, “Čech” if you search for “cech”, etc.

          It should imo only be used for fuzzy searching doubles, which you probably will do with ToUpper

          You can’t just use ToUpper for comparisons due to issues like you mentioned, and the Turkish i problem. You need to do proper case-insensitive comparisons, which is where the Unicode case folding rules are used.

          offtopic: The eszett strictly speaking was a ligature for ‘sz’, which Hungarian orthography kinda preserved while for German the separated version is ‘ss’, and there’s plenty of such stuff in nature.

          Thank you for saying that more clearly.

      But then you run into the issue of incredibly trivial impersonation on any email service which doesn’t reserve all variants of registered names

        Yes, email as it really exists kinda sucks, but the idea was nice. When it ran over UUCP, LOL.
