All (or at least nearly all) of the characters needed to represent Urdu
are in the Arabic script block. Essentially Persian uses the Arabic
script with a few additional characters, and Urdu uses what Persians use
plus a few more additional characters.

Section 8.2 of the Unicode Standard 4.0 begins with, "The Arabic script
is used for writing the Arabic language and has been extended for
representing a number of other languaes, such as Persian, Urdu, Pashto,
Sindhi, and Kurdish. Urdu is often written with the ornate Nastaliq
script variety." The latter sentence, as Val Ziegler pointed out, is
simply refers to a stylistic/presentational variation as far as Unicode
is concerned.
