Or read the file with
read.table(file("umlaut.txt", encoding="MAC"), ...)

I have a file containing names of German students. These names
contain the characters "ä", "ö" or "ü" (German umlauts). I use
read.table() to read the file and let's assume the table is then
stored in a variable called "data". The names are then contained in
the first column, i.e. data[,1]. Now if I simply display the variable
"data", I see, that "ä" is replaced by \x8a, "ö" is replaced by \x9a
and so forth.
This is strange. When I have a file umlaut.txt
Name
Äserich
Ömadel
Übermunsch
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:
umlautasis
Name
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[T1]{fontenc}
\usepackage{textcomp}
\usepackage{babel}
\usepackage[latin1]{inputenc} % For ü,ä

Thing is that \x9a for o-umlaut is an unusual encoding:
> names(which(sapply(iconvlist(),iconv, x="S\x9aren")=="Sören"))
[1] "CP1282" "CSMACINTOSH" "MAC"
[4] "MAC-CENTRALEUROPE" "MACINTOSH" "MACIS"
[7] "MAC-IS" "MAC-SAMI"
> iconv("öäüÖÄÜ", to="MAC")
[1] "\x9a\x8a\x9f\x85\x80\x86"
and accordingly,
> data$names <- iconv(data$names,from="MAC")
> data
names points
1 Björn 10
2 Sören 20
or, if you need to do it for many variables, this should work:
ix <- sapply(data, is.character)
data[ix] <- lapply(data[ix], iconv, from="MAC")
