So I a file SetACL dump that I was trying to parse with Perl, found that the file encoding was UCS2-Little Endian. I was reading the file into perl and wanted to standardize the formatted output I would generate.
$line = decode('UCS-2LE',$oldline);
#answers found here
#also saw possible answers here
#perl -MEncode -le "print for Encode->encodings(':all')"
