Problems with non-English character.

Question

Hi
My problem is that '������' become rubbish in my c++ dll. I hope someone can help me.
---Java code-----
class Test
     private native void print(String str);
     public static void main(String [] args)
          new Test().print("������");
     static
          System.loadLibrary("Test");
----c++ code----
JNIEXPORT void JNICALL
Java_Test_print(JNIEnv *env, jobject obj, jstring jstr)
     const char * str = env->GetStringUTFChars(jstr, 0);
     if (str == NULL) {
          return; /* OutOfMemoryError already thrown */
     wstring str2(200, ' ');
     MultiByteToWideChar(CP_ACP, 0, str, strlen(str)+1, (LPWSTR)str2.data(),strlen(str));
     printf(">>> %s\n\n", str);
     cout << " str: " << str << ", str2.data: " << str2.data() << endl;
     return;
----OutPut-----
&#9500;�&#9500;�&#9500;�&#9500;�&#9500;�&#9500;&#9570;str: &#9500;�&#9500;�&#9500;�&#9500;�&#9500;�&#9500;&#9570;, str2.data: 02CB6118
Thanks

Hi,
You will probably see the same rubbish if you try to print them to the console using java. Dos prompts usually have problems to print the Swedish characters. I don't know if this will affect your c++ dll or not. But you can specify the encoding for the JVM (-Dfile.encoding). For valid encodings see:
