So, recently Firebug has started popping up with the following error on a number of pages I’ve created or visited:
The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must to be declared in the document or in the transfer protocol.
After a bit of Googling, the solution presented itself. Place the following code between your <head></head> tags and not only will the error go away, but your page will render right!
<meta http-equiv=“Content-Type” content=“text/html; charset=utf-8” />
