-# Test that the SQLite routines for converting between UTF encodings
-# produce the same results as their TCL counterparts.
-#
-# $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.
-#
-# Coverage:
-#
-# sqlite_utf8to16be (step 2)
-# sqlite_utf8to16le (step 1)
-# sqlite_utf16to8 (steps 3, 4)
-# sqlite_utf16to16le (step 5)
-# sqlite_utf16to16be (step 5)
