# This file implements regression tests for SQLite library. The focus of
|
|
# this file is testing the SQLite routines used for converting between the
|
|
# various suported unicode encodings (UTF-8, UTF-16, UTF-16le and
|
|
# UTF-16be).

# The rough organisation of tests in this file is:
|
|
#
|
|
# enc2.1.*: Simple tests with a UTF-8 db.
|
|
# enc2.2.*: Simple tests with a UTF-16LE db.
|
|
# enc2.3.*: Simple tests with a UTF-16BE db.
|
|
# enc2.4.*: Test that attached databases must have the same text encoding
|
|
# as the main database.
|
|
# enc2.5.*: Test the behaviour of the library when a collation sequence is
|
|
# not available for the most desirable text encoding.
|
|
# enc2.6.*: Similar test for user functions.
|
|
# enc2.7.*: Test that the VerifyCookie opcode protects against assuming the
|
|
# wrong text encoding for the database.
|
|
# enc2.8.*: Test sqlite3_complete16()
