+# $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. |
