This and a number of tests whose expected results are revised are very
interesting. 

Apparently, whoever took them and added to the layout tests overlooked the fact
that the original tests were served via an HTTP server that emits 'Content-Type:
text/html; charset=UTF-8'.  

When blink layout tests are run without a web server, they're interpreted as the
default encoding (of content_shell which is windows-1252/iso-8859-1). So, all
the expected results have been wrong until now. 

I've filed https://bugs.chromium.org/p/chromium/issues/detail?id=597517 for
that. 

I propose that you add a separate layout test to test UTF-8 encoding detection
rather than relying on these layout tests (virtually all of them whose expected
results are changed from gibberish to something meaningful fall into that
category).

Thanks for filing the bug. Are you going search for all the files to update them
with the meta tag yourself? Feel free to split the work and assign it to me.
