I'm trying my best to understand this thread, but I'm having difficulty.

Please stop trying, there is nothing for you here, read Tutorials/perlunitut: Unicode in Perl, perlunitut, use via:File::BOM

I've tried deleting it using all these commands, none of which works:

Please stop that :) Read perlunitut, use via:File::BOM , it will decode your file and remove the BOM for you

If you've got raw data you want to share you can use 

perl -MData::Dump -MFile::Slurp -e " dd scalar read_file shift, { qw/ 
+binmode :raw / }; "  AnyKindOfInputFile > ThatFilesBytesAsPerlAsciiCo
+de.pl

The different ways BOM can look 

 
$ perl -MFile::BOM -MData::Dump -e " dd \%File::BOM::enc2bom "
{
  # tied Readonly::Hash
  "iso-10646-1" => "\xFE\xFF",
  "UCS-2"       => "\xFE\xFF",
  "UTF-16BE"    => "\xFE\xFF",
  "UTF-16LE"    => "\xFF\xFE",
  "UTF-32BE"    => "\0\0\xFE\xFF",
  "UTF-32LE"    => "\xFF\xFE\0\0",
  "UTF-8"       => "\xEF\xBB\xBF",
  "utf8"        => "\xEF\xBB\xBF",
}
