A bit of font trivia for inquiring minds out there. %20 = a space in 8
bit Ascii (the % acts as a flag which says "the next string of numbers
is the code for a character" and 20 is the ascii (also unicode) for a
space (in hex). A few other common ones are %2C = comma, %3A = colon,
%3B = semicolon, and %25 = percent.
