There seems to be an issue with the haven (1.1.1) package when including any type of special character in the file path, including just the file name.
Assuming this is a real issue I am looking for some kind of neat hack/solution to get around it.
An (not ideal) example would be to have R take a copy of the file into a more friendly path and give it a "better" filename and then load with haven. Such as:
setwd("c:/temp")
fn <- "randóóm.sav"
file.copy(paste0("./äglæpath/", fn), fn)
file.rename(fn, gsub("[^-\\./a-zA-Z0-9[:space:]]", "", fn))
# now apply read_sav() to the copy
I'm using:
R version 3.5.0 (2018-04-23)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows >= 8 x64 (build 9200)
563
Unfortunately, I have been able to reproduce the problem on Windows 10 with both the standard version of haven and the devtools version of haven. This appears to be known bug with haven. #371
Move the file to a directory without German Umlauts in the file path or filename. Thus, your workaround works as stated.

Read_*() does not work for special characters in file path #371 https://github.com/tidyverse/haven/issues/371
the problem code is in DfReader.cpp df.parse_dta() 594-612 in haven/src/DFReader.cpp.
