将普通C++字符串写入Rapid JSON会导致字符串带有反斜杠

#include <iostream>
#include <rapidjson/writer.h>
#include <rapidjson/stringbuffer.h>
#include <rapidjson/reader.h>
#include <rapidjson/encodings.h>

int main() {
    const char* cString = "Hello\\World";
    std::string jsonString;

    rapidjson::StringBuffer stringBuffer;
    rapidjson::Writer<rapidjson::StringBuffer> writer(stringBuffer);

    rapidjson::Transcoder<rapidjson::UTF8<>, rapidjson::ASCII<>> transcoder;
    transcoder.Put(reinterpret_cast<const rapidjson::UTF8<>*>(cString), strlen(cString));
    transcoder.Flush();

    writer.String(reinterpret_cast<const char*>(transcoder.Peek()), transcoder.Size());

    jsonString = stringBuffer.GetString();

    std::cout << "JSON String: " << jsonString << std::endl;

    return 0;
}
