A short while after contacting the site (see Tweets below), the site did start working so maybe they fixed something with their site, after I contacted them, or maybe it was a temporary glitch with my browser. Personally I think Wikipedia is easier to use for copying then pasting unusual characters.
The Wikipedia pages are Geometric Shapes Unicode block and Miscellaneous Symbols or Dingbat.

@2045singularity they are not images. The invisible flash movie is there to do the actual copy functionality, nothing more.
