  Modular transformations of string theory are shown to play a crucial role in
the discussion of discrete flavor symmetries in the Standard Model. They
include CP transformations and provide a unification of CP with traditional
flavor symmetries within the framework of the "eclectic flavor" scheme. The
unified flavor group is non-universal in moduli space and exhibits the
phenomenon of "Local Flavor Unification", where different sectors of the theory
(like quarks and leptons) can be subject to different flavor structures.
