  26       In many scripts, transforming the input
  27       sequence into the final layout often requires some combination of
  28       operations—such as context-dependent substitutions,
  29       context-dependent mark positioning, glyph-to-glyph joining,
  30       glyph reordering, or glyph stacking.
  31     </p>
  32 <p>
  33       In some scripts, the shaping rules require that a text
  34       run be divided into syllables before the operations can be
  35       applied. Other scripts may apply shaping operations over
  36       entire words or over the entire text run, with no subdivision
  37       required.
  38     </p>
  39 <p>
  40       Other scripts, do not require these
  41       operations. However, correctly shaping a text run in
  42       any script may still involve Unicode normalization,
  43       ligature substitutions, mark positioning, kerning, and applying
  44       other font features.
