如何将WCHAR_T*转换为jstring？

#include <jni.h>

jstring WCHARToJString(JNIEnv* env, const wchar_t* wcharStr) {
    // Step 1: Convert WCHAR_T* to Unicode string
    int unicodeLen = ::WideCharToMultiByte(CP_UTF8, 0, wcharStr, -1, NULL, 0, NULL, NULL);
    char* unicodeStr = new char[unicodeLen];
    ::WideCharToMultiByte(CP_UTF8, 0, wcharStr, -1, unicodeStr, unicodeLen, NULL, NULL);

    // Step 2: Convert Unicode string to UTF-8
    int utf8Len = ::MultiByteToWideChar(CP_UTF8, 0, unicodeStr, -1, NULL, 0);
    char* utf8Str = new char[utf8Len];
    ::MultiByteToWideChar(CP_UTF8, 0, unicodeStr, -1, utf8Str, utf8Len);

    // Step 3: Convert UTF-8 string to jstring
    jstring jstr = env->NewStringUTF(utf8Str);

    delete[] unicodeStr;
    delete[] utf8Str;

    return jstr;
}

JNIEXPORT jstring JNICALL Java_com_example_Converter_convertWCHARTojstring(JNIEnv* env, jobject obj, jstring wcharStr) {
    // Step 0: Convert jstring to WCHAR_T*
    const jchar* jstr = env->GetStringChars(wcharStr, NULL);
    jsize length = env->GetStringLength(wcharStr);
    const wchar_t* wstr = (const wchar_t*)jstr;

    // Call helper function to perform the conversion
    jstring result = WCHARToJString(env, wstr);

    // Release the jstring and WCHAR_T* memory
    env->ReleaseStringChars(wcharStr, jstr);

    return result;
}
