症状

The following error appears in Confluence pages:

The issue ONLY occurs when the attachment name contains a German umlaut character. 

When trying to add/select a File Name from Insert 'Office Powerpoint' macro window setting, you can see both the correct attachment name and one that is not, as in this screen shot:

診断

To avoid problems with character encoding, make sure that UTF-8 encoding is used across these components in your environment:

• データベースの文字エンコーディング
• Application Server URL encoding
• Confluence の文字エンコード

If the problem persists even after ensuring that UTF-8 is applied across the above components, you most probably have a misconfiguration in your proxy setting. To check this, access Confluence directly via <localhost/IP>:<http-connector-port> (e.g., localhost:8090), update the Base URL setting in Confluence Admin > General Configuration to reflect the new URL, and check if the same issue still occurs.

原因

There is a misconfiguration in the proxy configuration.

ソリューション

• You can apply the UTF-8 URIEncoding parameter to the AJP connector if you are using mod_jk, and add the following option to your Apache mod_jk configuration:

  <Connector port="8009" protocol="AJP/1.3" URIEncoding="UTF-8"/>
  JkOptions +ForwardURICompatUnparsed
  

• If the problem persists, configure Confluence to use mod_proxy instead of mod_jk
