Someone should sue FACT for copyright infringement – and refuse to settle.
In US law, there is no such thing. The shape of a glyph (or many) isn't even slightly copyrightable. This is settled law. Fonts (on computers) have a special status that makes them semi-copyrightable in that some jackass judge from the 1980s called them "computer programs" and so they have the same protection as software... but this won't protect against knockoffs.
This person isn't just collecting existing letter shapes; inventing a new letter shapes would be protected by copyright?
It is settled law that letter shapes aren't copyrightable. Period.
