The ?-meson leptonic widths, ?ee and ???, are obtained, respectively, from the e+e? forward–backward asymmetry and the ?+?? cross section around the ?-mass energy. We find ?ee = 1.32 ± 0.05 ± 0.03 keV and sqrt{?ee???} = 1.320 ± 0.018 ± 0.017 keV. These results, compatible with ?ee = ???, provide a precise test of lepton universality. Combining the two results gives ??? (?) = 1.320 ± 0.023 keV
