Good point. The `cur' is `nntp-server-buffer' (" *nntpd*") or
`gnus-work-buffer' (" *gnus work*") as the case may be. Gnus uses
those buffers for various purposes. Although there looks no
situation where it is necessary to have multibyte data as far as
I can observe, Gnus explicitly sets them as multibyte buffers (see
`nnheader-init-server-buffer' and `gnus-set-work-buffer'). I
believe the reason they do so is to prevent from breaking data
when copying them to another multibyte buffer (IIUC, copying data
from a multibyte buffer to a unibyte buffer causes no problem).
So, I didn't modify those buffers' multibyteness. If I introduced
a new unibyte work buffer (such as " *gnus binary work*"), it
required that `gnus-read-active-file-2' binds `nntp-server-buffer'
to it for example. It is used by all the back ends but I'm not
sure it never causes a problem with them all.
