German umlauts causing troubles

We are running JIRA 7.3.5 and Confluence 6.1.2

Confluence pages with German umlauts in the title lead to wrong characters in JIRA issue links.

Umlauts in the summary of a Service Desk ticket also causing the "Related knowledge base articles" lookup to fail:

Can someone give me a hint which encoding setting might cause this problem?

Hi Andreas,

we had a similar problem with Jira macros in Confluence and JQL containing German special characters. Maybe it's the same problem on your side.

The problem were two wrong system properties on the Confluence side:

<sun.jnu.encoding>ANSI_X3.4-1968</sun.jnu.encoding> <file.encoding>ANSI_X3.4-1968</file.encoding>

 We had to change both properties to:



to get rid of the problem.

Thanks for your quick answer, Thomas.

Where do I changes this properties exactly? Do I use one of the approaches described here:

I added both parameters to our System Properties but the problem still exists after rebooting Confluence and JIRA.

Does anyone have an idea of a different cause of this problem?

I was able to fix this by adding the JVM arguments also to the JIRA server configuration.

Thanks again for your support, Thomas!

Liebe Grüße aus Wien
