Encode::DoubleEncodedUTF8 - Fix double encoded UTF-8 bytes to the correct one
use Encode;
use Encode::DoubleEncodedUTF8;
my $string = "\x{5bae}";
my $bytes = encode_utf8("\x{5bae}");
my $dodgy_utf8 = $string . $bytes; # $bytes is now double encoded
my $fixed = decode("utf-8-de", $dodgy_utf8); # "\x{5bae}\x{5bae}"
Encode::DoubleEncodedUTF8 adds a new encoding utf-8-de and fixes double encoded utf-8 bytes found in the original bytes to the correct Unicode entity.
The double encoded utf-8 frequently happens when strings with UTF-8 flag and without are concatenated. See encoding::warnings for details.
