I think that both pi and I are universal constants in sage. sage: zeta_symmetric(pi) 0.583573760763662 sage: zeta_symmetric(1/2) 0.497120778188314 sage: zeta_symmetric(1/2+I) ....exception sage: zeta_symmetric(1/2+CC(I)) 0.485757429670983 - 1.38777878078145e-17*I
Conclusion: it seems that coercion to a complex number happens for pi but not for I (even though zeta_symmetric expect a complex number as input).
