A natural question arises if the Riemann zeta-function in Theorem 1 can be replaced by other zeta-functions which are universal in a certain strip?

Summary
For a region G on the complex plane, let us denote by H(G) the space of analytic functions on G equipped with the topology of uniform convergence on compacta. This, the continuity of the function hn and Theorem 5.1 from [1] together with Lemma 1 show that the measure PT,n converges weakly to Pn = mH h−n 1 as T → ∞. By the definition of the random element Xn(s, s), Pn Hεv ≥ 1 − ε for all n ∈ N This means that the family of probability measures {Pn : n ∈ N} is tight, and, by the Prokhorov theorem, it is relatively compact. Using an equivalent of the weak convergence of probability measures in terms of continuity sets, Theorem 2.1 of [1], we have by Lemma 5 that lim νT ζ(s + iτ, s + iτ, α, ω; a, F ) ∈ A = P (A).
