It is today PVALID (as it matches rule A), so it will be added as an
exception to the Exception table.
This is what the Exception table is designed for, so it does not
damage the philosophy (more than the fact that we (IETF) should limit
the number of exceptions I think -- and trust what UTC has said about
the various codepoints).
