[Li Da <sculida@…>]

there is a json file like this, without bom, use gbk code set. The boost::property_tree can parse it successfully in the majority.

try {
    boost::property_tree::read_json(filename, tree);
}
catch (exception &e) {
    cerr << e.what() << endl;
}

However, if the file has chinese character"历"(c0fa)or"繞"(c040), the property_tree will throw exception"invalid code sequence"

the code set gbk is simalar to gb2312,gb18030
