> go against symbols in domain names Can you clarify which symbol it was? The only related problem I know is that homoglyphs in domain names are problematic due to their potential abuse for phishing. So for example a smallcaps letter O or C that looks like a lowercase o or c would be problematic. Edit in response: The Apple symbol  (U+F8FF) is not cross-platform. It’s explicitly defined as a code point that a system (OS X in this case) can define for its own “private use.” Given this, it’s not surprising that it would go against ICANN policy and cause problems in various browsers.
