If you use an internationalized version of QueueMetrics for a language based on a non-Latin character set, you may find yourself unable to write strings in your own language (e.g. the name of a queue) into QueueMetrics. This is usually not caused by QueueMetrics itself (that is completely UTF-8 compliant) but by the underlying MySQL instance.

In order to make sure that your charset is accepted by your database:

1. Make sure that MySQL is installed in/for your language.
2. Run the following commands on all tables of the database but the queue_log table:
   ALTER TABLE `call_status` CHARACTER SET utf8;
ALTER TABLE `pause_codes` CHARACTER SET utf8;
....
   This tells the database engine to accept UTF-8 on all storage tables.
3. Modify the connection string in web.xml so that it ends with:
   ....&useUnicode=true&characterEncoding=utf8&characterSetResults=utf8
   This tells the MySQL connector to force UTF-8 encoding when talking to the datbase server.

In our experience this is usually all that is needed to run an Unicode datbase instance.
