Does any one know what tags and special characters are supported by Udemy's batch question upload csv template?

We have questions that contain new lines and code snippets. The CSV template shows that text can be put inside quotes but it is not accepting HTML or any other special characters. But it does not contain any example that shows line breaks, bold, italics, code, etc. For example, how should the following problem statement be encoded in the csv:

"Given the following code, what will be the output?
class TestClass{

  public static void main(String args[]){

  {

      System.out.println("hello");

   }

}"
