Hi,
I spent last day with setting up the UTF-8 encoding in xwiki. I set
all thing according to offical guide, but i had question marks instead
of letters in my database. I realized that i must set up hibernate. So
I made some changes in my hibernate.cfg.xml file. I added these to
lines.
<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">UTF-8</property>
it working perfect now. It may help to someone, who will have the same problem.
