Oh, now I get it.  I had missed the part where it says "character data
immediately follow the base structure".  And the bit about the "UTF-8
data, the UTF-8 length and the wstr length" are not describing the
contents of those fields, but rather where the data can be alternatively
found since the fields don't exist.
