I noticed that as well, and welcomed it - it loads perceptibly faster too. I think they stopped using some long "private range" UTF-8 characters and switched to shorter "private range" ones, which may have reduced the actual byte count. Some private range UTF-8 characters require 4 bytes to express, and I noticed that the same glyphs that were in the longest private range in the -9 edition are now shorter 3-byte private range characters, like the left-pointing arrow in the Appendix B tables which in the -9 edition were "\xF4\x80\x81\x89" are "\xEF\x81\xA6" in the -10 edition. Other such character substitutions could reduce total size by quite a lot.
