Very nice and amazingly accurate. But am I using your website the right way? When I look through the characters in the search results, if I see one that isn't rendering on my computer and just has a block instead of the symbol. I've been clicking on "bad" for "rate this suggestion". Thinking that it tallies up the total good/bad for a character to mean "how likely people are to have this character installed and working on their computers".
However, I now have a feeling that's not what that feature is for.
My guess was that the Good/Bad rating is to help with some sort of Machine Learning going on the background. E.g. the way I draw my Ampersand might be slightly different than yours, so if either or both of us see the result we were hoping for (&), that should get our Good rating. If it returns an (8), it may or may not deserve a Bad. If something way off appears as a top result (^), that would be pretty Bad.
