+#
+# $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.
