问如何检查文件是否为文本文件？

EN

use Data::TextOrBinary;
say is-text('/bin/bash'.IO);                            # False
say is-text('/usr/share/dict/words'.IO);                # True

given slurp("read-utf8.p6", enc => 'utf8') -> $f {
    say "UTF8";
}

use strict;
use warnings;

use File::Type;

my $file      = '/path/to/file.ext';
my $ft        = File::Type->new();
my $file_type = $ft->mime_type($file);

if ( $file_type eq 'application/octet-stream' ) {
    # possibly a text file
}
elsif ( $file_type eq 'application/zip' ) {
    # file is a zip archive
}
