Unfortunately, changing from <meta charset="utf-8">VARCHAR to <meta charset="utf-8">VARBINARY is just impossible at this stage since several versions of eXo JCR 1.12 have already been released and those version would then be incompatible. Moreover, I'm pretty sure that it will create side effects more painful than case sensitivity issues.<div>

</div></div>We can easily change this by making the table use VARBINARY for the<br>
field instead of VARCHAR. There is a jira for here<br>
<a href="https://jira.jboss.org/jira/browse/JBEPP-334" target="_blank">https://jira.jboss.org/jira/browse/JBEPP-334</a> with a patch attached.<br>
Someone working on the JCR will need to make this change.<br>
