Following eariler work of Kubota and Mennicke, the major work of Bass, Milnor and Serre [1] constructed characters of congruence subgroups of the modular subgroups of SL(n) and Sp(2n) over a totally complex number field, which are related to the power residue symbol. They do not obtain the lowest possible level of these Kubota characters, nor does it appear possible to modify their arguments to extend the characters to the lowest possible level.
