Maybe it was not clear on my message but I did mentioned that I'm using Rgui.

Regarding the Windows version it is Windows 2000 Professional.

Moreover, the problem does not seem to be a OS or locale problem, as I'm using 
the same locale under ESS or under Rgui and the behaviour is different. 
Moreover, using exactly the same portuguese word (salário) under two 
different contexts, one as an object name, and the other as a data frame 
column name, the behaviour of R is different (but only under Rgui and not 
under ESS, as I've tried to shown on the trace I've send in the previous 
message).

In any case my locale info (on both ESS and Rgui) is:

On Rgui:
> Sys.getlocale()
[1] 
"LC_COLLATE=Portuguese_Portugal.1252;LC_CTYPE=Portuguese_Portugal.1252;LC_MONETARY=C;LC_NUMERIC=C;LC_TIME=Portuguese_Portugal.1252"

On ESS:

> Sys.getlocale()
[1] 
"LC_COLLATE=Portuguese_Portugal.1252;LC_CTYPE=Portuguese_Portugal.1252;LC_MONETARY=C;LC_NUMERIC=C;LC_TIME=Portuguese_Portugal.1252"

Reflecting a bit more on this issue I think a possible explanation for this 
different behaviour is that ESS uses Rterm and not Rgui, which means that 
Rterm and Rgui apparently are acting differently with the same instructions, 
in spite of the locale information and OS settings being exactly the same.
