Since the PostScript file can be edited with a text editor, one could
easily change the notice to assert rights of the person who created
it - but is that legal? I wonder whether the original assertion is
valid.
Well...your copyright applies ONLY to the font (i.e. the shape and
design of the characters). Any information you make available over the
internet or on some digital storage medium is NOT copyrighted... but,
should someone make that same data available using your copyrighted
font, it is the LETTERS/NUMBERS/USW. that are violating copyright...
NOT the information itself!
