unable to delete attachments which contain the character é

[JoeI]

An employee uploaded a few attachments and was unable to delete some of them. We realized that the only attachments with the problem were the ones with the character é in the file name. As a temporary workaround, we've renamed the attachments to omit the character.

Thanks to help from Atlassian Support, we learned that there were two reasons that we were unable to delete attachments with special characters:

1. It seems that our Lockpoint plugin had gotten corrupted.
2. Tomcat lacked an encoding setting.

The fixes:

1.

• Review the contents of WEB-INF/lib and WEB-INF/classes. Compare them with a vanilla install
  • Back them up
  • Remove any non standard jars
• Stop Confluence
• Empty the contents of all folders in your <confluence-home> directory that have the word 'plugin' in the folder name:
  • <confluence-home>/plugin-cache
  • <confluence-home>/plugins-osgi-cache
  • <confluence-home>/plugins-temp
  • <confluence-home>/bundled-plugins
  • <confluence-home>/bundled-plugins_language
• Restart Confluence.

2.

Added the missing tag "URIEncoding=UTF-8" to the tomcat connectors configuration.

If this is specific to the core application I would raise a support request as it may be a bug or may be related to database storge, the support peeps are best to advise. http://support.atlassian.com

Thanks, Andy. I created support issue CSP-90414 at the same time that I posted the question, and I'll update Atlassian answers once I have a resolution to share that's better than the workaround. :)
