I suspect that the problem is not related to the version, but to
what you might have set on LANG.

Maybe if we add something like:
	LANG=C.utf-8

to the Documentation/Makefile or adding:

	.. -*- coding: utf-8; mode: rst -*-

as the first line on the *.rst file that include the kernel-doc 
directive would solve the issue.
