    Unicode Definitions:

    UNICODE

    Defining this symbol causes all db.*'s internal string handling,
    e.g. filenames, user id, lock manager name etc, to be done with
    widechar strings.

    On Unix systems there is not much point in defining UNICODE,
    as all disk I/O and network protocol functions take single-byte
    character strings as arguments. Thus db.* must convert any Unicode
    strings to single-byte strings before calling these functions.
    Unicode strings require more memory (on Unix, four times as much)
    as single-byte strings.

    UNICODE_DATA

    Defining this symbol enables support for widechar data fields.
    Support for Unicode fields does not require db.* library to be
    compiled with UNICODE defined (i.e. Unicode fields can still be
    handled even if internal string manipulation is ANSI / ascii).
