Re: [R] =?iso-8859-1?q?New_problem_printing_=B0C_in_plots?=

That this prints as an octal escape was always the intention: it is your OS that is telling R that it is not a printable character. What locale are you in? For me

1) In en_GB this works (correct, as that is charset ISO-8859-1)
2) In C, I get "25\260C" (correct, as that is not an ASCII char)

My guess is that you have R running in a C locale and emacs in a UTF-8 locale, since the UTF-8 representation of that symbol is c2b0, in octal \302\260. If that is what is going on, 1.8.1 would have been equally confused (it might have printed UTF-8, but it would not plot it), so I suspect the important change is not the one you think it is.

Note that at least one set of RPMs now runs R in the C locale (but that's not part of R per se). If you run in en_NZ I think you will find R works to your taste. The good news is that R-devel already supports en_NZ.utf8, and so 2.1.0 will in a couple of months.

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


BTW, the plot device matters too.

In earlier versions, I used to get this:

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?


Neither of those, is my guess.
