I forgot the actual hex values I am using. These values are from the example input files shown above and using the 003d conversion in %conv also shown above.

Here are my input file hex values (pre-conversion) from the input file:

U+feff U+005b U+004b U+0045 U+0059 U+005d U+000d U+000a
U+0000 U+4e0d U+000a
U+0028 U+4e0d U+000a
U+003f U+4e0d U+000a
U+0036 U+4e0d U+000a
U+005b U+4e0d U+000a
U+004b U+0065 U+0079 U+0053 U+0074 U+0072 U+003d U+0000 U+4e28 U+4e3f 
+U+4e36 U+4e5b U+4e0d U+000a
U+004b U+0065 U+0079 U+004d U+0061 U+0070 U+003d U+0000 U+4e28 U+4e3f 
+U+4e36 U+4e5b U+4e0d U+000a
U+005b U+0044 U+0049 U+0043 U+0054 U+005d U+000d U+000a
U+0000

and here are my hex values for outputting (post-conversion) to the new file (where the 003d conversion shown above is the only one):

U+feff U+005b U+004b U+0045 U+0059 U+005d U+000d U+000a
U+0000 U+4e0d U+000a
U+0028 U+4e0d U+000a
U+003f U+4e0d U+000a
U+0036 U+4e0d U+000a
U+005b U+4e0d U+000a
U+004b U+0065 U+0079 U+0053 U+0074 U+0072 U+006b U+0065 U+0079 U+0031 
+U+0000 U+4e28 U+4e3f U+4e36 U+4e5b U+4e0d U+000a
U+004b U+0065 U+0079 U+004d U+0061 U+0070 U+006b U+0065 U+0079 U+0031

Again, many thanks.
