I asked a fellow Gentoo developer from Ukraine, and he confirms that
using Y for koi8-u would be "strange". He also made the suggestion to
use K for all koi8*, even if it would collide with Korean. It should be
obvious from the buffer's content if it's (e.g.) Russian or Korean, so
there isn't any real ambiguity.

Interestingly, the following comment (by RMS) in cyrillic.el goes into
the same direction:
