Indicate charset in format_html() output

[nalimilan]

format_html currently does not output any information regarding character encoding used in the output. In that case, ISO-8859-1 is assumed. But R strings are typically in UTF-8. This means any non-ASCII characters are not interpreted correctly by web browsers.

This can easily be fixed by adding the following output to the HTML:

 <meta http-equiv="Content-Type" content="text/html;charset=UTF-8"> 

Cf. http://www.w3schools.com/html/html_charset.asp

Thanks for the suggestion. However, format_html is intended to produce code that can be included in other HTML documents. Adding a meta tag would likely make this impossible.
