No. That user name does not contain UTF-8. It looks like an HTML-escape, since Perlmonks converts all usernames that don't really fit into ASCII into their plaintext &#xxxx; equivalents and renders these explicitly. Trying to register a name with a homoglyph will instead create a name containing the appropriate ampersand escape. Ampersand-escapes are always rendered with a visible ampersand and not passed through.
