Thanks a lot for this clear answer. So there is no way to preserve our french cultural exception (accented characters), if we want to be international... I have thought that the inclusion of a parameter encoding in data function (e.g. data(mydata,encoding="latin1")) like in the function 'file' could be an way to solve the problem. Apparently, the problem is much more complicated...
