114 DIN Legibility Standard
116 The recent German DIN 1450 legibility standard
117 recommends several features for font legibility, including
118 differentiation of letter shapes to reduce confusion. The Go fonts
119 conform to the 1450 standard by carefully differentiating zero from
120 capital O; numeral 1 from capital I (eye) and lowercase l (ell);
121 numeral 5 from capital S; and numeral 8 from capital B. The shapes of
122 bowls of b d p q follow the natural asymmetries of legible Renaissance
123 handwriting, aiding differentiation to reduce confusion. [5]
126 Mistaking S for a 5 (at certain sizes) is more of a problem... but... Ze Germans
