+Subject: [PATCH] Fix functional API tests to be endian-agnostic
+
+Fix the "backslashreplace" tests for the functional API to be
+endian-agnostic.  The tests used to rely on `.encode("utf-16")`
+producing the same data as found in the test file.  However, on big
+endian platforms it would produce a big endian encoding, while the test
+file is little endian.  To avoid the problem, explicitly specify
+`utf-16-le` encoding.  Since this meant that the BOM is no longer
+produced, explicitly include it in input.
+
+Fixes #312
