Hello Henrique,

Yeah, DOS cyrillic encodings is hell of a mess (good article on topic,
you may already know, is http://czyborra.com/charsets/cyrillic.html).
The RUSCII.GIF is known as codepage number 1125 ie CP1125. And there is
some uncertainty about code points FAh & FBh. While some sources
suggests that there must be middle dot and square root - There is
article on wikipedia.org about different variants of DOS 866 code page -
http://ru.wikipedia.org/wiki/CP1125 . It is in russian tough, but you
can search the page for "CP1125". You'll find that RUSCII.GIF is
actually a symbols chart for CP1125 as wikipedia means it. Other sources
suggests that there must be division sign and plus-minus sign - I found
this chart http://ascii-table.com/codepage.php?1125 but also it would be
interesting to have a look at the "IBM documentation", you mentioned.
And the best thing in this story, is that "Republic standard of Ukraine
RST 2018-91"
(http://www.terena.org/activities/multiling/koi8-u/ukrcod2018-91win.html) 
doesnt'
describe anything at all beyond code point F9h, so code points FAh-FFh
could look anything you like.
