This is strange. When I have a file umlaut.txt


and read it in with 

umlaut = read.table("umlaut.txt", header = TRUE)
umlautasis = read.table("umlaut.txt", header = TRUE,as.is = TRUE)

I get the following in both cases: 

1    Äserich
2     Ömadel
3 Übermunsch

This is on Windows Vista. I use it every day without ever having seen nasty
codings, typically with the following in latex

\usepackage[latin1]{inputenc} % For ü,ä
