------------------------------------------------
bq.can we use unicode escapes?
Am not sure on the question here? We could use unicode escape character also.
See the test case added in TestVisibilityLabels. It tries to add unicode
characters with unicode escape character.
> [Visibility Controller] Support UTF8 character as Visibility Labels

> This would be an action item that we would be addressing so that the
> visibility labels could have UTF8 characters in them. Also allow the user to
> use a client supplied API that allows to specify the visibility labels inside
> double quotes such that UTF8 characters and cases like &, |, ! and double
> quotes itself could be specified with proper escape sequence. Accumulo too
> provides one such API in the client side.
