It seems quite confusing to me. ISTR that there was an extended discussion about classifying non-breaking spaces on this list a while back. But I can't find it now. Does anyone remember the details? I am not sure we are talking about the same question. The issue I am raising is not one of classifying it, it is that these two different character codes get used and I don't see an explanation of what's going on.
