I've tested it here, http://www.fileformat.info/info/unicode/utf8test.htm
No talking about the miscellaneous ones.
Is it Windows 7 fonts? Is it Chrome rendering? Is it some configuration I should tweak? Any help is welcome!
I've just checked that UTF-8 was selected in Chrome codification, and it was. Strangly I can see more symbols in IE 11 (!)
