Description of problem: Unlike claimed by its extension, the sun12x22.psfu.gz font doesn't have a Unicode mapping. See here for more information: http://dev.laptop.org/ticket/1653 I confirmed that the codeset of the font is CP437, seen at /usr/share/i18n/charmaps/IBM437.gz. I have attached a corrected version of the font to that bug. Use psfgettable to compare the tables.
I've sent this to upstream maintainers now. Can be closed.
