I can confirm this for Xubuntu herd 4, daily build for 25th february. However, in the installed system the keyboard layout is the one specified during installation (i.e. Finnish, in this case) and I can type characters specific to that layout - the file manager (Thunar) cannot recognize those specific characters in filenames, though.
