Two ways in which it works:

1) $ cat t4.sh
   #!/bin/sh

   export INPUT='$1$iW95z/HB$GFcYFxMKK6x8EUPglVkux.'
   echo "1 ==="$INPUT"==="
   export MD5PW=$(echo -n "$INPUT" |  hexdump -v -e '" " 1/1 "%02d"')
   echo "2 ==="${MD5PW}"==="
   echo -n "3 ==="
   echo ${MD5PW} | tr ' ' '\n' |
   while read i; do
       echo $i | awk '{ printf("%c", $i) }';
   done
   echo "==="
   $ ./t4.sh
   1 ===$1$iW95z/HB$GFcYFxMKK6x8EUPglVkux.===
   2 === 36 49 36 105 87 57 53 122 47 72 66 36 71 70 99 89 70 120 77 75 75
   54 120 56 69 85 80 103 108 86 107 117 120 46===
   3 ===$1$iW95z/HB$GFcYFxMKK6x8EUPglVkux.===
   $



2) $ cat t4-2.sh
   #!/bin/sh

   export INPUT='$1$iW95z/HB$GFcYFxMKK6x8EUPglVkux.'
   echo "1 ==="$INPUT"==="
   export MD5PW=$(echo -n "$INPUT" |  hexdump -v -e '" " 1/1 "%02d"')
   echo "2 ==="${MD5PW}"==="
   echo -n "3 ==="
   for i in ${MD5PW}; do
        echo $i | awk '{ printf("%c", $i) }';
   done
   echo "==="
   $ ./t4-2.sh
   1 ===$1$iW95z/HB$GFcYFxMKK6x8EUPglVkux.===
   2 === 36 49 36 105 87 57 53 122 47 72 66 36 71 70 99 89 70 120 77 75 75
