I have seen my URL's and links failing, due to missing UTF-8 support. Also, every upgrade of JIRA og Confluence replaces server.xml (but not setenv.sh)

The Connector

Add URIEncoding="UTF-8" to the Connector as in:

<Connector className="org.apache.coyote.tomcat4.CoyoteConnector" port="80" address="77.243.52.139" minProcessors="5"
                   maxProcessors="75"
                   enableLookups="false" redirectPort="8443" acceptCount="10" debug="0" connectionTimeout="20000"
                   useURIValidationHack="false" URIEncoding="UTF-8"/>

 

The Java VM

Add -Dfile.encoding=UTF-8 to the JAVA_OPTS as in:

JAVA_OPTS="-Xms1024m -Xmx1024m -XX:MaxPermSize=512m $JAVA_OPTS -Djava.awt.headless=true -XX:NewSize=512m -Dfile.encoding=UTF-8"

On windows (nooo!) is might be adding -Dfile.encoding=ISO-8859-1
