I already tried it and failed.  The line

@documentencoding ISO-2022-JP

is not effective in the Japanese text encoded by the iso-2022-jp
coding system.  euc-jp and euc-japan or shift_jis, shift-jis and
sjis also do not the trick.  They cause an error as follows:

emacs-w3m-ja.texi:8: warning: unrecognized encoding name `ISO-2022-JP'.

Is the makeinfo v4.8 too old?  It misidentifies `@' contained in
the raw file contents as the commands.
