One of my friend had a similar domain but he got it refunded
because it didn't worked in all browsers etc and would not in future either according to him because of ICANN's specs
which 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.
