Symptoms

When creating question in Confluence Question using special character like Russian (Cyrillic) or other than International alphabet, the title will be encoded wrongly in the Confluence Question editor. This happens when the instance is using SSL and proxy and only happens in Confluence Question not during creating normal page.

Diagnosis

Diagnose the issue following Troubleshoot Character Encoding documentation.

Cause

It's caused by the following:

• Missing useURIValidationHack attribute
• useBodyEncodingForURI attribute is set to true
• No Tomcat termination in the connector tag

Resolution

Add the following attribute in the SSL connector and ensure the SSL termination is configured in Tomcat:

• useURIValidationHack="false"

• useBodyEncodingForURI="false"

• className="org.apache.coyote.tomcat4.CoyoteConnector"
