Using readxl 1.0.0 in R 3.4.0 for Windows, I recently came across an unexpected error when trying to open an Excel file containing a non-ASCII character in the file name. Depending on the encoding of the path variable, the import either works or fails:
> library(readxl)
> # Copy an example file to a path including a special character
> my.path <- "Tür.xlsx"
> file.copy(system.file("extdata", "datasets.xlsx", package="readxl"), my.path, overwrite = TRUE)
[1] TRUE
> # Try to open file with path in native encoding
> read_excel(enc2native(my.path))
# A tibble: 150 x 5
