detect_raw_enc(charToRaw(utf8))

# function to read file as raw bytes
read_bin <- function(x) readBin(x, raw(), file.size(x))

# detect encoding of files read as raw vector
ex_path <- system.file("examples", package = "uchardet")

# deutsch text as binary data
de_bin <- read_bin(file.path(ex_path, "de", "windows-1252.txt"))
detect_raw_enc(de_bin)
