1. Replace the existing
{CROWD}
/apache-tomcat/bin/setenv.sh and setenv.bat files with the attached.
2. Restart your Crowd instance and perform an XML Backup (Admin -> Backup).
3. Make sure you have the attached setenv files in your new Crowd installation as well and restart.
This will allow you to import the XML backup containing UTF-8 characters.
This has now been resolved.
All files now exported by Crowd enforce UTF-8 as their default encoding and do not rely on the default system encoding.
