In the thread of bug#5387, I wrote this:

It seems that Gnus is not yet using coding-system-from-name.

This will probably work.

But I'm not sure it is a bugfix since there're some ways for a user
to tell Gnus that ms950 is cp950 (e.g. `mm-charset-synonym-alist').

I've installed it in Emacs trunk (i.e. Emacs 24) and Gnus trunk.
This thread should be closed.

P.S. Gnus trunk has been tagged with `emacs_23_2_RC' before sync'ing
with Emacs 24.
