You are right, '!=' should have been 'ne'.

The code I posted simply stores/remembers any value that isn't 'W'.
Because I assumed that the length column has only one value to remember (per character), I used a variable instead of an array for the length column.

Whenever you encounter a new character name in the loop, call a subroutine to output the previous character. I.e. add the following line before the other lines I posted:

if ($array[0]!='W') {
  OutputCharacter($char,$count,$length,@id);
  @id=();
}

The subroutine OutputCharacter just prints one line per value in @id, and in the first line also the name, count and length. One way to do that is to print the first line separately and then the rest in a loop
