Why did you add .characters8()?  It's wrong.

             if (upperC != c) {
                 c = upperC;
                 variant = SmallCapsVariant;
             } else {
                 variant = NormalVariant;
             }
         } else {
             variant = NormalVariant;
         }
     }
