I think it is the other way around: Tcl/Tk speaks UTF-8, so if you run R in a Latin-1 locale, you need to translate the strings to UTF-8. iconv() is your friend.

I'm a bit puzzled, though. The underlying C function RTcl_ObjFromCharVector tries to be smart about encodings, and the only way I can reproduce anything looking like your issue is if I do sneaky things like 

> x <- iconv("¡GUI de estadística", to="latin1")

[1] "\xa1GUI de estad\xedstica"

BTW: Notice that the Nabble interface is closing down. You need to use the mailing list directly.
