I have a web application being an instance of the SnipSnap wiki (please see I need to export the data. Unfortunately, one table space has mixed collations and I need someone who can convert this table space to UTF-8. I get the following error in the Tomcat log:

java.lang.RuntimeException: JDBCTemplate: unable to execute query [...]
java.sql.SQLException: Illegal mix of collations (latin1_general_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='
at com.mysql.jdbc.SQLError.createSQLException(

If someone could solve my problem, that would be great.

If you are able to do the complete migration from SnipSnap to Confluence (see, your offer is also highly welcome.

If you have a passion with wikis: besides the SnipSnap wiki, I have an addtional XWiki instance (see that needs to be migrated to Confluence too.

Also follow-up development offers are possible in the area of Confluence. Anyway, your first bid should focus on solving my MySql encoding problem to get to know each other. Thanks!
