-# 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()
