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,

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")
