The character is U+1F609 WINKING FACE.

Its regular UTF-8 encoding is f09f9889, which matches your error. Java expects Modified UTF-8, however:

Characters with code points above U+FFFF (so-called supplementary characters) are represented by separately encoding the two surrogate code units of their UTF-16 representation. Each of the surrogate code units is represented by three bytes. This means, supplementary characters are represented by six bytes, u, v, w, x, y, and z.

You cannot use NewStringUTF for this, you will have to manually decode from UTF-8.

Cribbing from my answer here, we will do the equivalent of
Charset.forName("UTF-8").decode(bb).toString():

const char * filename = /* what you have now */;
jobject bb = env->NewDirectByteBuffer(filename, strlen(filename));

jclass cls_Charset = env->FindClass("java/nio/charset/Charset");
jmethodID mid_Charset_forName = env->GetStaticMethodID(cls_Charset, "forName", "(Ljava/lang/String;)Ljava/nio/charset/Charset;");
jobject charset = env->CallStaticObjectMethod(cls_Charset, mid_Charset_forName, env->NewStringUTF("UTF-8"));

jmethodID mid_Charset_decode = env->GetMethodID(cls_Charset, "decode", "(Ljava/nio/ByteBuffer;)Ljava/nio/CharBuffer;");
jobject cb = env->CallObjectMethod(charset, mid_Charset_decode, bb);
env->DeleteLocalRef(bb);

jclass cls_CharBuffer = env->FindClass("java/nio/CharBuffer");
jmethodID mid_CharBuffer_toString = env->GetMethodID(cls_CharBuffer, "toString", "()Ljava/lang/String;");
jstring str = env->CallObjectMethod(cb, mid_CharBuffer_toString);
// Do something with str

Facing a similar issue currently and for me was working on an android project. Before I could go deep into diagonising the problem I opted to INVALIDATE CACHE AND RESTART and yeah it worked.
