Comment (by liweitianux):

 I recently upgraded to Xapian v1.4.1, and the Chinese query parser works
 as expected.
 Here is the new and **correct** behavior:

 {{{
 #!python
 xapian.version_string()
 # '1.4.1'

 qp = xapian.QueryParser()
 qp.add_prefix("subject", "S")
 qp.add_prefix("s", "S")
 qp.add_prefix("body", "B")
 qp.add_prefix("b", "B")
 qp.add_prefix("", "B")
 qp.add_prefix("", "S")

 qstr1 = "中文"
 q1 = qp.parse_query(qstr1)
 print(q1)
 # Query(((B中@1 AND B中文@1 AND B文@1) OR (S中@1 AND S中文@1 AND S文@1)))
 }}}

 I also tried to rebuild recent `mu` (see issue
 https://github.com/djcb/mu/issues/123 ), and now the Chinese search works.

 Thank you!
