# 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 behavior of the library when a collation sequence is
|
|
# not available for the most desirable text encoding.
|
|
# enc2.6.*: Similar test for user functions.
|
