      abstract     = {We construct symmetry-preserving lattice regularizations of
                      2d QED with one and two flavors of Dirac fermions, as well
                      as the `3450' chiral gauge theory, by leveraging
                      bosonization and recently-proposed modifications of
                      Villain-type lattice actions. The internal global symmetries
                      act just as locally on the lattice as they do in the
                      continuum, the anomalies are reproduced at finite lattice
                      spacing, and in each case we find a sign-problem-free dual
                      formulation.},
