/**
* Unicode special character support
*
* Detection is made by testing missing glyph box rendering against star character
* If widths are the same, this "probably" means the browser didn't support the star character and rendered a glyph box instead
* Just need to ensure the font characters have different widths
*
* Warning : positive Unicode support doesn't mean you can use it inside <title>, this seams more related to OS & Language packs
