In Unicode you are allowed to assign private characters http://en.wikipedia.org/wiki/Mapping_of_Unicode_characters#Private_use_characters The U+200D ZERO WIDTH JOINER could also be used but most browsers will not support it - you need a font that supports your character anyway. http://blogs.msdn.com/michkap/archive/2006/02/15/532394.aspx In summary: Unicode is just a subset of all characters which have been used for written communication and whether a character gets included depends not only on objective properties but on lobbying and other circumstances. The deeper you dig the more nasty Unicode gets - as all complex formats and standards.
