Handle Japanese Characters
When the character encoding of XML documents is UTF-8, it is necessary to convert UTF-8 characters to Shift_JIS by using KDDI extention functions for displaying characters on mobile phones used in Japan.
In order to use C++ wrappers for KDDI extention functions, SophiaFramework.hpp should be included after TARGET_EXTENSION_KDDI macro is defined.
