improper encoding in confluence.cfg.xml

The encoding of confluence.cfg.xml is UTF-8. If the site welcome message (corresponding to property "property.sitewelcomemessage" in the file) contains non UTF-8 characters (e.g. "ä", "ö", or "ü") these are not UTF-8 escaped when written to confluence.cfg.xml.

This in turn causes Confluence at restart of the application server to overwrite the file with the default configuration and enter the Confluence setup sequence. IOW the old configuration file is lost! The following is printed to the server log:
