/*
 * Note 1: the system must have the correct Locale, in order for the test to
 * work correctly, on those systems that do not comply, the test will succeed.
 * Here are some guidelines to set the locale correctly.
 * On Windows: ControlPanel->Regional Settings,
 *             ensure that "Japanese" is selected and checked, and in
 *             "Code page conversion tables", the following must be checked,
 *             932 (ANSI/OEM - Japanese Shift-JIS).
 * On Unix: use "locale -a" verify one of these exist ja_JP.UTF-8 or
 *          ja_JP.utf8 or ja_JP.ujis, and export one of them with LC_ALL.
 *
 *
 * Note 2: since we need to set the locale, it is safest to execute this test
 * in its own VM (othervm mode), such that the ensuing tests can run unperturbed,
 * regardless of the outcome.
