  In a consistent top-down approach based on orbifold compactifications,
modular and traditional flavor symmetries combine nontrivially to the so-called
eclectic flavor symmetry. We extend this scheme from two extra dimensions,
discussed previously, to the six extra dimensions of string theory. By doing
so, new insights on the nature of CP and its spontaneous breaking emerge.
Moreover, we identify a new interpretation of R-symmetries as unbroken remnants
from modular symmetries that are associated with geometrically stabilized
complex structure moduli. Hence, all symmetries (i.e. modular, traditional
flavor, CP and R) share a common origin in string theory: on a technical level,
they are given by outer automorphisms of the Narain space group. The eclectic
top-down approach leads to a very restrictive scheme with high predictive
power. It remains a challenge to connect this with existing bottom-up
constructions of modular flavor symmetry.
