Subject Re: Using Accumulo shell to add column visibility to cells containing Unicode values
Date Mon, 26 Aug 2013 20:20:17 GMT
What version are you using? According to ACCUMULO-241, you should be able
to quote any UTF-8 characters for visibility using the Java API. The shell
will likely have parsing issues, however.
