Actually, it applies to the Emacs startup on MS-DOS.

The node you quoted is from an appendix that describes the MS-DOS port
of Emacs, which uses codepage.el.  On other systems, Emacs uses a
different implementation of code pages, the one from code-pages.el.
That package is simply not documented; if we want to document the code
page facilities on systems other than MS-DOS, that information should
be added somewhere else in the manual, not in the DOS appendix, IMHO.
