    14 * Description:     This module is a plug-in module for Shift-JIS with Pictograph.

    15 *                Basicaly, Vodafone Pictograph is encoded by ISO2022,

    16 *                but Japanese FEP needs a pictograph as one character code

    17 *                in Shift-JIS character code set.
