Reordering and shaping have different requirements. Reordering can be
done based only on the codepoints, whereas shaping needs also intimate
knowledge of the fonts being used. The former can be done by a
text-mode application, the latter cannot, not anywhere close to what
readers of the respective scripts would expect.
