[R] New problem printing °C in plots

In ESS, I get  "25\201\260C"

The °C does end up in the plot alright, but it has an accented A as
well which is not useful.

(The '°C' I get from within Emacs using C - x 8 - o)
GNU Emacs 21.3.1



In earlier versions, I used to get this:

> version
         _
platform i686-pc-linux-gnu
arch     i686
os       linux-gnu
system   i686, linux-gnu

language R
> paste("25", "°C", sep = "")
[1] "25°C"
>

That plotted fine.  I can't remember if the problem existed with
R-2.0.0 and I didn't notice a mention the NEWS file/s -- but that
could be because I didn't know what to look for.

Could this be purely an Emacs problem, or does it have to do with
changes in R-2.x.x?

TIA
