As Brian probably already knows, the issue is likely to be that your 
source file is in a non-UTF-8 encoding. (Emacs has become a little too 
smooth in handling such files almost invisibly. The magic incantation is

C-x RET f utf-8

before saving.)

It can be reproduces as follows:

[pd at titmouse2 ~]$ cat > xxx.R
"æøå"
[pd at titmouse2 ~]$ iconv -t latin1 xxx.R > xxxx.R

and then R-patched gives

 > source("~/xxxx.R")
Error in source("~/xxxx.R") :
  invalid multibyte character in mbcs_get_next at line 1

whereas R-2.6.2 gives

 > source("xxxx.R")
 > .Last.value
$value
[1] "\xe6\xf8\xe5"

$visible
[1] TRUE
