Abstract
We show that if $C_\varphi$ is a Hilbert-Schmidt composition operator on an appropriately weighted Hardy space, then there exists a capacity, associated to the weight sequence of the space, so that the set on which the radial limit of $\varphi$ is unimodular has capacity zero. This extends recent results by Gallardo-Gutiérrez and González.
