I can see '?' chars instead of i18n (8859-2) charactes in text mode installer on Disk Druid screen (*only* on this screen, other screens are Ok). Performed installation in Czech language.
Same goes for Icelandic (ISO-8859-1). If Im not mistaken the same thing also happens during the package installation with the text in the pacjage description (from specs.po)
