We examine bosonic zero modes of vortices formed in the gauge breaking G'H. For non-Abelian G, zero modes are generic. Their solutions depend on global symmetry structure. Vortices render the embedding H G space dependent, with a dynamically determined subgroup H single valued. They Aharonov-Bohm scatter gauge bosons associated with multivalued generators. Alice strings (H=O(2), H=openZ2) attract charges and scatter SO(2) photons, and a two-string system has zero modes with unlocalizable Cheshire charge. The resulting superconductivity has novel electrodynamics.
