Apparently Apple uses U+F8FF, part of the Unicode "Private Use Area", to represent its logo. It's not surprising that it fails to render on non-Apple platforms, given this warning in http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/CORPCHAR.TXT http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/CORPCHA... : # The following (1) is for the Mac OS Roman encoding # (also used in Symbol & Croatian). # NOTE: The graphic image associated with the Apple logo character is # not authorized for use without permission of Apple, and unauthorized # use might constitute trademark infringement. 0xF8FF # Apple logo # Roman-0xF0, Symbol-0xF0, Croatian-0xD8 Additional references: http://hea-www.harvard.edu/~fine/OSX/unicode_apple_logo.html http://hea-www.harvard.edu/~fine/OSX/unicode_apple_logo.html http://www.fileformat.info/info/unicode/char/f8ff/index.htm http://www.fileformat.info/info/unicode/char/f8ff/index.htm https://en.wikipedia.org/wiki/Private_Use_Areas https://en.wikipedia.org/wiki/Private_Use_Areas
