Also, how about using the -e sed param in PercentizeNull() and DepercentizeNull() to reduce the number of sed processes run:
Code:
PercentizeNull()
{
  sed -e "s/%/%25/g" -e "s/\x0/%00/g"
}



Thanks, Chubler_XL.

It was indeed awkward of my code to invoke "sed" consecutively multiple times. The subroutines should be polished as you suggested.

Code:
#percent-encoding for null character
PercentizeNull(){
  sed -e "s/%/%25/g" -e "s/\x0/%00/g"
}
DepercentizeNull(){
  sed -e "s/%00/\x0/g" -e "s/%25/%/g"
}



In addition, the following method with semicolon also spares consecutive multiple invocations of "sed".

Code:
#percent-encoding for null character
PercentizeNull(){
  sed 's/%/%25/g ; s/\x0/%00/g'
}
DepercentizeNull(){
  sed 's/%00/\x0/g ; s/%25/%/g'
}
