We study Pomeron-Odderon interference effects giving rise to charge and single-spin asymmetries in diffractive electroproduction of a π+π− pair. The final state interactions and the role of f0 meson are discussed. The absence of f0 signal in the charge asymmetry observed by HERMES may be due to the smalness of its quark component.
