TokenID = BBF7B1E82D75939E9F29FCC59F0EF542;
UserID = 18;                                              

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
NSLog(@"Customer Add/Edit JSON Object %@",[maindict description]);
[manager POST:kWSUrlAddCustomerVendor parameters:maindict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

} progress:^(NSProgress * _Nonnull uploadProgress) {

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    [SVProgressHUD dismiss];
    NSDictionary *dict = (NSDictionary *)responseObject;
    NSLog(@"%@",[dict description]);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];

Response:

data =     {
    AddressList =         (
                    {
            AddressID = 2056;
        }
    );
    CompanyID = 1;
    MobileNo = 345345345334;
    Name = "\U00e0\U00aa\U00b9\U00e0\U00aa\U00bf\U00e0\U00aa\U00b0";
    TaggedToIDList =         (
                    {
            ID = 4866;
        }
    );
    isActive = 1;
};
message = "Customer Created successfully";
status = Success;

Problem is in 'Name' field
