Guess encoding of file

Uses stringi::stri_enc_detect(): see the documentation there for caveats.

Usage

guess_encoding(file, n_max = 10000, threshold = 0.2)

Arguments

file

A character string specifying an input as specified in datasource(), a raw vector, or a list of raw vectors.

n_max

Number of lines to read. If n_max is -1, all lines in file will be read.

threshold

Only report guesses above this threshold of certainty.

Value

A tibble

Examples

guess_encoding(readr_example("mtcars.csv"))
#> # A tibble: 1 × 2
#>   encoding confidence
#>   <chr>         <dbl>
#> 1 ASCII             1
guess_encoding(read_lines_raw(readr_example("mtcars.csv")))
#> # A tibble: 1 × 2
#>   encoding confidence
#>   <chr>         <dbl>
#> 1 ASCII             1
guess_encoding(read_file_raw(readr_example("mtcars.csv")))
#> # A tibble: 1 × 2
#>   encoding confidence
#>   <chr>         <dbl>
#> 1 ASCII             1
