When I use these as variable names in a data.frame, odd things happen:

I your variables only include numbers (or only characters), this works

XX <-  cbind(a=1, å=2, ä=3, ö=4, æ=5, ø=6)
> XX
     a å ä ö æ ø
[1,] 1 2 3 4 5 6
But this doesn't
> data.frame(XX)
  a å ä X. Xæ X.
1 1 2 3  4  5  6

i.e. it is the data.frame function that manages to mess up the variable names for us Windows users
