Unicode is garbled

Unicode in HTML documents is garbled when loading URLs in the browser.

Background:

To render both images and HTML currently everything is loaded as binary and thus non-ASCII text is not correctly decoded. Apparently XHR needs to be told in advance whether binary data or text is expected and thus doesn't leave us with many choices.

Solutions:

• Find a workaround for loading both types through once request
• Do 2 requests worst case, a second one in case the first was the wrong binary/text setting
• Detect content tpye from path extension (.png, .gif, .jpe?g -> binary, * -> text)

Quick spike shows that using XHR2 it is possible to load a blob from binary and text sources, and then depending on the MIME header use FileReader.readAsBinaryString() or FileReader.readAsText()), so option 1 is looking good.
