Here is a table of some ukrainian characters and their keycodes that are missing from the standard KOI8 cyrillic font. If you have your KOI8-U ukrainian fonts properely installed in your system, you should be able to see the letters in the first column of the table. The X Windows keyboard mod map allows you to type ukrainian characters at the keyboard.
Installation is through the xmodmap utility, using the Caps Lock key to toggle the modes.
Alternatively, the xrus utility allows users to toggle easily between the default font and the new definition. After installing the utility, type xrus yawerty.koi8u.xmm to try it out.
