------------------------------------------------
+1 on documenting the way we should use Authorizations, the way labels are
specified and using quotes on Cell Visibility.
bq.new Authorizations("\"CONFIDENTIAL&PRIVATE\"");
In this example what I would think is we it is just simple for the user to say
("CONFIDENTIAL&PRIVATE"). May be those escape sequences are themselves not
needed. Its bit tricky if we don;t have proper documentation.
If we try to add this behaviour to Authorization in the future seeing what
issue users are facing in a future JIRA, is that the right way to approach
this?
Not only in authorizations we need to do this but also in addLabels. Ensure
that before doing addLabels we need to strip the double quotes and the escape
character that we add.

> 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.
