OK, but then where is it documented that "S D e" in Gnus Summary is
supposed to read the draft saved by "C-c C-d" in the mail buffer?
Could it be that these two are not supposed to work together?

The node "Drafts" in the Gnus manual describesa different procedure.
If I follow it, then after typing "D e" in the nndraft:drafts group, I
get placed in the *unsent mail* buffer with the correct Cyrillic text.

Nickolai, did you try to use these different commands in your
scenario?
