This is also my last attempt.
YOU USE THIS AT YOUR OWN RISK!
I discovered that Windows CP 1252 certainly does have these characters as single bytes in it.

Code:

#!/bin/sh

# Windows 1252 code page 8 bit values, (with UTF-8 unicode values shown)...

NULLS=$'\x80\x80'
REG=$'\xAE'
TM=$'\x99'
FILENAME="${NULLS}"'Word Finder'"${REG}"' Plus'"${TM}"

# Should be 20 characters long.
echo "${#FILENAME}"

echo "${FILENAME}"

hexdump -C <<< "${FILENAME}"

##### !!!YOU USE BELOW AT YOUR OWN RISK!!! #####
# rm -f "${FILENAME}"

Example printout:
