Installer does not load russian font, if text mode is selected. As following, it's impossible to read anything on the screen. bootnet.img does load russian font, but it still does not add lines "SYSFONT=Cyr_a8x16" and "SYSFONTACM=koi2alt" to /etc/sysconfig/i18n, and keyboard value to /etc/sysconfig/keyboard. In addition, Cyr_a8x16.psf is broken since 1994, and koi2alt format is obsolete. As a replacement, UniCyr.psf has to be used with with koi8-r.acm for Russian language and with koi8-u.acm for Ukrainian language. I've just attached archive with fonts and maps to bug id 9519. This font may also be used for microsoft-cp1251 encoding with microsoft-cp1251.acm (present in archive). This archive will also be attached to this bug id.
