Description

The composer' html items do not respect the character encoding declared within HTML pages when loaded via entering a URL.

Steps to reproduce:
1. Create a new composer, and add an html item onto it
2. In the html item's URL text box, enter "http://www.licadho-cambodia.org/?khmer"
3. Hit Refresh HTML
4. When the page is drawn, you'll notice a lot of ÁÁÁÁÁÁÁ characters, indicating that the character encoding used to render the page is set to something other than UTF-8 (the declared encoding of the loaded page)

Load the above-mentioned page in your browser to see how it should normally look with proper encoding. I'm attaching a screenshot which should also help.

Whatever underlying QT web tech the html item is using, if it can't detect a given page's character encoding, it surely allows for a default character encoding to be set, which should be UTF-8 to insure greatest compatibility with what's out there.

It's a pretty significant issue when it comes to making sure QGIS works for everyone around the globe.

Setting the priority to high as I am not sure if this regressed, or if it was always like that.
