R help - Nov 2002 - Problem with accented characters in portuguese

Dear all,
I've recently encountered a strange behaviour when using R with portuguese 
accented characters. The most curious aspect is that using the same code with 
ESS under XEmacs the behaviour is different.
My system is:
> R.version
         _              
platform i386-pc-mingw32
arch     i386           
os       mingw32        
system   i386, mingw32  
status                  
major    1              
minor    6.1            
year     2002           
month    11             
day      01             
language R

Here it goes a trace of the "problem":

First under Rgui
> sal?rio <- 45    # this is ok!
> sal?rio
[1] 45
> objects()
[1] "sal?rio"
> d <- data.frame(sal?rio=c(34,45),name=c('xyz','fgd')) #
this is NOT ok!
> d
  sal.rio name
1      34  xyz
2      45  fgd
> d$sal?rio
NULL
> d$sal.rio
[1] 34 45


Now with ESS 5.1.20 under XEmacs 21.4
> sal?rio <- 45
> sal?rio
[1] 45
> d <- data.frame(sal?rio=c(34,45),name=c('xyz','fgd'))
> 
> d
  sal?rio name
1      34  xyz
2      45  fgd
> d$sal?rio
[1] 34 45


Another "funny" thing about this is that is does not happens with all
accented
characters of Portuguese. Check this trial whether I've used a column with a
name using almost all accented characters of Portuguese:

In Rgui
> d2 <-
data.frame(??????????????=c(34,45),name=c('xyz','fgd'))
> d2
  X.??????????.?? name
1              34  xyz
2              45  fgd

As you can see the problem occurs with ? and ?, and not with the other 
accented characters.

In Ess:
> d2 <-
data.frame(??????????????=c(34,45),name=c('xyz','fgd'))
> d2
  ?????????????? name
1             34  xyz
2             45  fgd


Thank you for any help.

This is a function of your OS: you haven't told us the version of Windows,
nor what locale it thinks you are in, nor if you are using Rterm or Rgui.
But it doesn't really matter, as we can't do anything about it. Some
aspect of Windows seems to think some of your accented characters are not
valid in the locale it thinks you are in.  That you are seeing difference
probably reflect different codepages.
