+# Test that the SQLite routines for converting between UTF encodings

+#
+# $testname is the prefix to be used for the test names.
+# $str is a string to use for testing (encoded in UTF-8, as normal for TCL).
+#
+# The test procedure is:
+# 1. Convert the string from UTF-8 to UTF-16le and check that the TCL and
+# SQLite routines produce the same results.
+#
+# 2. Convert the string from UTF-8 to UTF-16be and check that the TCL and
+# SQLite routines produce the same results.
+#
+# 3. Use the SQLite routines to convert the native machine order UTF-16
+# representation back to the original UTF-8. Check that the result
+# matches the original representation.
+#
+# 4. Add a byte-order mark to each of the UTF-16 representations and
+# check that the SQLite routines can convert them back to UTF-8. For
+# byte-order mark info, refer to section 3.10 of the unicode standard.
+#
+# 5. Take the byte-order marked UTF-16 strings from step 4 and ensure
+# that SQLite can convert them both to native byte order UTF-16
+# strings, sans BOM.
