Subject [jira] [Commented] (ACCUMULO-739) Please add dot (.) as a valid character in column visibility tokens
Date Tue, 28 Aug 2012 19:31:08 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-739?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13443432#comment-13443432
] 

John Vines commented on ACCUMULO-739:
-------------------------------------

Escaping will make parsing substantially more complicated, especially if you start going into
nested quotations with some OTHER form of escaping. Perhaps an alternative for supporting
a larger alphabet would be to adopt a custom encoding which ensures that no multi-byte characters
consist of one of our reserved characters. This would allow us to continue to do speedy checks
while still expanding the user base outside of English without concerns of encodings breaking
their expressions.
