# 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.
