Unicode character in R-package Authors Name

Question

Lots of European authors have Unicode characters in their names such as Å, Æ, ø and Ä. How can they have their actual name with these Unicode characters rather than some transformed version of the English alphabet (Å -> A, Æ -> A, Ä -> A) when creating R-package. In short, how can I use Unicode characters in author/creator/maintainer name when creating an R-Package.

There is some note here: http://r-pkgs.had.co.nz/check.html

I quote:

If you use any non-ASCII characters in the DESCRIPTION, you must also specify an encoding. There are only three encodings that work on all platforms: latin1, latin2 and UTF-8. I strongly recommend UTF-8: Encoding: UTF-8
