It's right in Chapter 1, in the list of SVN Features:

  Consistent data handling -- Subversion expresses file differences
  using a binary differencing algorithm, which works identically on
  both text (human-readable) and binary (human-unreadable) files. Both
  types of files are stored equally compressed in the repository, and
  differences are transmitted in both directions across the network.

It's also on the front page of the website.

But maybe you're right, maybe it should be in Appendix A as well. :-)
