    Sorry, I cannot see this. The example was about Schiller in Fraktur
    or Roman ("Antiqua"). There is *no* difference in orthography
    between Fraktur and Antiqua (= normal Latin) in German.
    Why are normal Latin and Fraktur separate (sub-)scripts in ISO 15924
    when the argument is different orthographies?

    There is no orthographic difference between Latf and Latn
    in German.

    What are the orthographic differences between Hans and Hant?

    For example, Nastaliq has U+06C1 and U+06C3
           where Naskh has U+0647 and U+0629.

    I suspect that many Arabs have difficulties reading Persian or Urdu

    Nastaliq is a *two-dimensional* script as can be seen from
    the following sample images.

    I consider the difference between Naskh and Nastaliq greater
    than between Latin and Latin (Fraktur) and perhaps comparable
    to Hans vs. Hant.
