Comment 7 for bug 1678018

I cannot reproduce this bug as reported i.e. with non-ascii characters in an object name, but I can get the symptoms by putting non-ascii chars in an x-object-meta metadata value [1]

The object path is quoted here [2] before being passed to send_put method so it is fine to decode as utf8.

But if there is non-ascii in a metadata value AND a metadata key that is unicode (as we have seen EC writes into diskfle) then the send_put will blow up when it attempts to join those into a string, at the same line as reported, but the "culprit" is not the object name.
