Fixed bug in 8 bit character output

8 bit charcters were not being properly output in the ruby script.
This has been corrected and the example table in README updated to show
the correct output.
Added a Python version of the script

Added an identical scrpt to the Ruby version written in Python.
Intended for Python 3 and not tested with Python 2.
Added a test script and reference output file

Added a bash script that compares the output of the two scripts against
a known reference output and then against each other.
