Please elaborate what's the problem in Gnus.

I don't see any asymmetry:

The above mentioned article is 2 years old.  The information there
probably is not accurate anymore for current CVS Emacs.  I don't
recall that (codepage-setup 1252) ever worked.

BTW: `rs-windows-1252.el' is obsolete; With recent CVS Emacs 22, you
don't even need it's replacement `rs-ucs-coding-system.el':
