They appear in ascending Unicode codepoint order, so "2" and "3" would come
first, then the two Chinese characters, I think in the order given.

If you pass -v to apitest it'll give more verbose output.  You can also
set environment variable VERBOSE for the same effect.

There's a "Running test programs" section in xapian-core/HACKING which
covers this and more.
