My version says the same. However, the implementation of
set-language-environment
contains the following snippet:

   ...
  (if language-name
      (if (symbolp language-name)
	  (setq language-name (symbol-name language-name)))
   ...

so, using a string is the right thing, but a symbol is currently working too.
(I must have seen 'utf-8 used somewhere and copied it without checking
the documentation :)
