These multicolored fonts can cause problems. E.g. firefox on linux was at one point rendering the unicode char "black right pointing triangle" as light blue for me despite the font and text around it being black! Can be fun for some, but not if you intend it to look like the text font! This character was in unicode since 1993 long before emoji existed and now we can't even insert a simple triangle in text without being certain it won't look ridiculous on some people's screens. http://www.fileformat.info/info/unicode/char/25b6/index.htm http://www.fileformat.info/info/unicode/char/25b6/index.htm
