Try #3 to fix the android layout tests crash in run-webkit-tests.

Try #3 to fix the android layout tests crash in run-webkit-tests.

This patch forcibly reencodes to ASCII at a different layer, matching
where we're actually seeing the stack trace. This seems like an
overly broad solution, but may at least get us past the crash so I can
see where things might really be failing.

This change also backs out the change in r182282, since it didn't seem
to help anything.

lgtm, thanks! It didn't fix android either ... I guess I thought I had already
reverted it :(.
