Comment(by Complainer):

 A situation where this becomes truly problematic:

 1. Create a user and edit his nickname (not username) to include accented
 characters. If you create a post using this user, the author will be
 displayed properly on the page, with all foreign characters.
 2. Export your posts. In the created XML file, the author of the post will
 still be saved properly.
 3. Import posts on a blank WP installation from created file.
 4. New users are created during the import process and their names are
 broken once again.
