I can confirm this is reproducible on the latest Nightly 46 - characters not displayed properly in the tab title and in the video's name.

The actual text inside that <title> element is:

  Dasoul&quot;E

followed by four bytes with values 204, 129, 194, 129 and then followed by:

  l No Te Da&quot; etc

The little "garbage" character shown there is a hexbox for U+0081, which is exactly 129, no surprise.  This is one of the Unicode control characters.

The page is UTF-8 encoded, since it sends this HTTP header:

  Content-Type: text/html; charset=utf-8

Those first three non-ASCII bytes are the UTF-8 encoding of U+0301, which is COMBINING ACUTE ACCENT.  That's the character the page actually wanted.

So the real problem is that they have a stray 0x81 byte in there.  Chrome doesn't show control characters like that.  We do, quite on purpose, so people are aware when they have garbage in their text instead of silently hiding it...
