java - UTF 8 Special Characters when converting JString to String in JNI -

i'm trying convert string jstring in jni, when string contains utf 8 special characters, doesn't seems saving in right way.

for example: “avda. espaᡬ 1” when should “avda. españa 1”.

this code:

jstr= env->newstringutf(str.c_str()); 

is there way convert jstring specifying utf 8 charset?

i copied these somewhere, added exception handling. work in production.

// jstring std::wstring std::wstring jstr2wsz(jnienv *env, jstring string) {     std::wstring wstr;     if (string == null)      {         return wstr; // empty string     }      try     {         const jchar *raw = env->getstringchars(string, null);         if (raw != null)         {             jsize len = env->getstringlength(string);             wstr.assign(raw, raw + len);             env->releasestringchars(string, raw);         }     }     catch (const std::exception ex)     {         std::cout << "exception in jstr2wsz translating string input " << string << std::endl;         std::cout << "exception: " << ex.what() << std::endl;     }     return wstr; }  // std::wstring jstring jstring wsz2jstr(jnienv *env, std::wstring cstr) {     jstring result = nullptr;     try     {         int len = cstr.size();         jchar* raw = new jchar[len];         memcpy(raw, cstr.c_str(), len * sizeof(wchar_t));         result = env->newstring(raw, len);         delete[] raw;         return result;     }     catch (const std::exception ex)     {         std::wcout << l"exception in wsz2jstr translating string input " <<     cstr << std::endl;         std::cout << "exception: " << ex.what() << std::endl;     }  return result;
