We have a sed filter which will eliminate this kind of backspacing.
You need to replace <BACKSPACE> by the backspace character, ASCII 8,
then put the script in a file, make it executable and try:

	no_ul inputfile > outputfile

#-----start of script------
# no_ul - remove underline backspace char underlining escape sequences
sed \
    -e '/_<BACKSPACE>/s///g' \
$*
#-----end of script------
