Generated .project-file misses encoding declaration

Hi,

I'm experiencing problems creating eclipse project files, if the project's description in pom.xml contains special characters like german umlauts (like "öüä"). Refreshing the eclipse workspace after running eclipse:eclipse results in the following message from eclipse:

"Errors occurred while refreshing resources with the local file system.
Failed to read the project description file (.project) for comworld-eventlisteners. The file has been changed on disk, and it now contains invalid information. The project will not function properly until the description file is restored to a valid state."

This is caused by the content of the .project's generated comment-tag containing the exact same description as in pom.xml. But the .project-file is generated without stating an encoding parser should use to read it. So, if I prepend the line
<?xml version="1.0" encoding="ISO-8859-15"?>
eclipse is able to read the file just fine.

Regards,
Stefan
