const LONG_TEXT: &str = "Typography is the art and technique of arranging type to make written language legible, \
   readable and appealing when displayed. The arrangement of type involves selecting typefaces, \
   point sizes, line lengths, line-spacing and letter-spacing, and adjusting the space between \
   pairs of letters. The term typography is also applied to the style, arrangement, and \
   appearance of the letters, numbers, and symbols created by the process. Type design is a \
   closely related craft, sometimes considered part of typography; most typographers do not \
   design typefaces, and some type designers do not consider themselves typographers.";
