title: If data contains commas, how to store it in csv?
body: <p>If the task is to create a csv file out of some data where commas may be present, is there a way to do it without later confusing which comma is a delimiter and which comma is part of a value? </p>
  
  <p>Obviously, we can use a different delimiter, replace all occurrences, or replace the original comma with something else, but for the purpose of this question let's say that modifying the original data is not an option and a comma is the only delimiter allowed.</p>
  
  <p>How would you approach something like this? Would it be easier to create the xls instead? Can you recommend any java libraries that handle this well?</p>
