This generates tables showing the 14 standard fonts in both

WinAnsi and MacRoman encodings, and their character codes.

Supply an argument of 'hex' or 'oct' to get code charts

in those encodings; octal is what you need for \\n escape

sequences in Python literals.

usage: standardfonts.py [dec|hex|oct]
