Library is crashed because of "no feature in text"

[mickeyzo12]

I put a string from any korean language: "유니코드 국제 회"
crash is occurred because of "no feature in text", this library work normally with english string like "hello world", how can i fix this issue?

Call from c++ via jni:

jmethodID detectSingle = env->GetStaticMethodID(clazz, "detectSingle", "(Ljava/lang/String;)Ljava/lang/String;"); // find method
if (detectSingle == nullptr) {
cerr << "ERROR: method void runDetect() not found !" << endl;
}
else {
text = "유니코드 국제 회";
// Construct a String
jstring jstr = env->NewStringUTF(text.c_str());
// Call the method on the object
jobject result = env->CallStaticObjectMethod(clazz, detectSingle, jstr); // call method
// Get a C-style string
const char* str = env->GetStringUTFChars((jstring)result, NULL);
resultString = str;
}

To Java:

public static String detectSingle(String text) throws LangDetectException { // <=== We will call this
detector = DetectorFactory.create();
detector.append(text);
try {
//System.out.println("Java run result: "+detector.detect());
return detector.detect();
} catch (LangDetectException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "";
}
