> Select text from a UTF8 encoded webpage, such as this one. It'll now be in the clipboard. Then go ahead and use the onpaste handler with dataTransfer to get the text/html content. That content will still be in UTF8. Now, base64 encode that content and put it in a data uri marked as utf8.

Inside of those span tags is an unrecognized UTF8 character, instead of typical spaces. So the user sees a bunch of missing character glyphs.

I don't observe this behavior. Namely, I don't see any elements with classname "Apple-converted-space" when I paste the contents. Could you give us more specifics about what content (precise steps to select content) is copied on which browser (exact revision), and then to exactly where this content is pasted. Ideally, we would like to have a reduction (some html file to reproduce this bug).
