增加代码：

/* *Windows的机种依存文字 PC-9800系列等，NEC的电脑在日本主流的时候曾独自被定义了文字13区分配。 **/static const unsigned short jisx0208_2uni_page2D[96] = {/* 0x2D20 - 0x2D2F */0xfffd, 0x2460, 0x2461, 0x2462, 0x2463, 0x2464, 0x2465, 0x2466,0x2467,0x2468, 0x2469, 0x246A, 0x246B, 0x246C, 0x246D, 0x246E,/* 0x2D30 - 0x2D3F */0x246F,0x2470, 0x2471, 0x2472, 0x2473, 0x2160, 0x2161, 0x2162,0x2163,0x2164,0x2165, 0x2166, 0x2167, 0x2168, 0x2169, 0xfffd,/* 0x2D40 - 0x2D4F */0x3349, 0x3314,0x3322, 0x334D, 0x3318, 0x3327, 0x3303, 0x3336,0x3351,0x3357,0x330D, 0x3326, 0x3323, 0x332B, 0x334A, 0x333B,/* 0x2D50 - 0x2D5F */0x339C, 0x339D, 0x339E, 0x338E, 0x338F, 0x33C4, 0x33A1, 0xfffd,0xfffd, 0xfffd, 0xfffd, 0xfffd, 0xfffd, 0xfffd, 0xfffd, 0x337B,/* 0x2D60 - 0x2D6F */0x301D, 0x301F, 0x2116, 0x33CD, 0x2121, 0x32A4, 0x32A5, 0x32A6,0x32A7, 0x32A8, 0x3231, 0x3232, 0x3239, 0x337E, 0x337D, 0x337C,/* 0x2D70 - 0x2D7F */0x2252, 0x2261, 0x222B, 0x222E, 0x2211, 0x221A, 0x22A5, 0x2220,0x221F, 0x22BF, 0x2235, 0x2229, 0x222A, 0xfffd, 0xfffd, 0xfffd};
