DEL is unicode codepoint U+007F, which is the byte 0x7F in UTF-8, not 0xFF. Perhaps you were thinking of ÿ which is codepoint U+00FF, which encodes to the bytes 0xC3 0xBF in UTF-8.

Here's an equivalent shell script that only uses bash builtins, so no other software required:

  #!/bin/bash 
  mac="\\x${1//:/\\x}" 
  wol="\xFF\xFF\xFF\xFF\xFF\xFF" 
  for i in {1..16}; do wol+="$mac"; done 
  printf "$wol" > "/dev/udp/$2/9"
