I spoke too soon.  Typed literally, it works.  But the "equivalent"
programmatic code does not:

(let ((v (getenv "EMACS_LANGENV")))
  (and v (progn
           (set-language-environment v)
           (set-terminal-coding-system (intern v))
           (set-keyboard-coding-system (intern v))
           (set-input-mode (car (current-input-mode))
                           (nth 1 (current-input-mode))
                           '8bit)
           (run-with-idle-timer
            5 nil 'message              ; Once, after 5 sec of inactivity
            "Switch Cyr/Lat by Ctrl-\\, Cyr-Yawerty/Cyr-GOST by f9 \\"))))

I get

    Debugger entered--Lisp error: (coding-system-error Cyrillic-KOI8)
      set-terminal-coding-system-internal(Cyrillic-KOI8)
      set-terminal-coding-system(Cyrillic-KOI8)

What did I do wrong?

Thanks,
Ilya
