KOI8 standards (was - email to and from Russia)

[Zenon M. Feszczak]

>KOI8r, KOI-8 ukrainian

Does anyone know of a document (hopefully available
over the airwaves) detailing the differences between
these two encodings?
Or is this KOI-8 Ukrainian simply a de facto standard?

The version of KOI8  worked out for the ER Fonts
(hats off to Gavin Helf, wherever he may roam)
supports Ukrainian without alienating Russian speakers,
or, conversely, supports Russian without alienating
Ukrainian speakers, both of which tasks are
rare enough accomplishments in the non-virtual world.

The question is whether this conforms to the above
mentioned KOI-8 Ukrainian and/or KOI-8r (which I
assume to be what people common refer to as KOI-8).

Anyone?
