I agree with Randy'a point here.

BGP rtr_id does not need to be a routable address - it just needs to be
unique 32 bits within the domain scope.

We have had this discussion already during RFC6286 and concluded that 4
octet is sufficient for any type of BGP mesh.

If anything I would propose to go opposite and to ask your implementation
to allow UTF-8 encoded BGP rtr_id format.

Rgs,
R.
