好吧，这是个很老的问题了，网上的解决方法也很多，之前因为jsoncpp解析u中文解析不出来挠过各种墙，再次分享出来给大家用。
打开json_reader.cpp，再Reader::decodeString( Token &token, std::string &decoded )方法上面添加转码方法，如下：
static inline void appendUnicodeToUtf8(unsigned int c, std::string &utf8) {
if (c < 0x00080) {
utf8 += static_cast(c & 0xFF);
} else if (c < 0x00800) {
utf8 += static_cast(0xC0 + ((c >> 6) & 0x1F));
utf8 += static_cast(0x80 + (c & 0x3F));
} else if (c < 0x10000) {
utf8 += static_cast(0xE0 + ((c >> 12) & 0x0F));
utf8 += static_cast(0x80 + ((c >> 6) & 0x3F));
utf8 += static_cast(0x80 + (c & 0x3F));
} else {
utf8 += static_cast(0xF0 + ((c >> 18) & 0x07));
utf8 += static_cast(0x80 + ((c >> 12) & 0x3F));
utf8 += static_cast(0x80 + ((c >> 6) & 0x3F));
utf8 += static_cast(0x80 + (c & 0x3F));
}
}
然后在Reader::decodeString( Token &token, std::string &decoded )方法修改为
if ( !decodeUnicodeEscapeSequence( token, current, end, unicode ) )
return false;
// @todo encode unicode as utf8.
appendUnicodeToUtf8(unicode, decoded);//开始转码
// @todo remember to alter the writer too.
}
OK，搞定了，再解析u编码时不用挠墙了
