I've just installed WordPress on my server to move all my old stuff that was spread out over multiple blogs to a new place. Importing Tumblr was easy. Importing BlogML, well, not so much. ;) It worked, but it messed up my umlauts. I used BlogML Importer (http://wordpress.org/extend/plugins/blogml-importer/) for that.
Is there any chance to somehow automatically fix that mistake?
