这主要是由json_parser_read.hpp里面的一个bug造成的，修改如下代码：

struct a_unicode

{
context &c;
a_unicode(context &c): c(c) { }
void operator()(unsigned long u) const
{
//u = (std::min)(u, static_cast<unsigned long>((std::numeric_limits<Ch>::max)()));

typedef typename std::make_unsigned<Ch>::type UCh;
u = (std::min)(u, static_cast<unsigned long>((std::numeric_limits<UCh>::max)()));

c.string += Ch(u);
}

};

如上修改在xcode和visual studio环境下编译正常，但在gcc环境下，可能需要修改typedef typename std::make_unsigned<Ch>::type UCh;为typedef typename make_unsigned<Ch>::type UCh;
