Use <meta charset=UTF-8> in HTML5

Use <meta charset=UTF-8> in HTML5

More succinct than <meta http-equiv="Content-Type" content="text/html;
charset=UTF-8" />.  HTML5 allows it because all browsers support it
anyway -- authors would forget quotes, leading to <meta
http-equiv=Content-Type content=text/html; charset=UTF-8 />, so browsers
all treat "charset" as an attribute of <meta> that does what you expect.
