I regularly use non-printable ASCII characters as delimiters. I just confirm first that they are not in the input. I am going to start using the ones you mentioned. This solution is one I rarely if ever see used. The other solution which I have seen in practice is to encode the comma character. The problem really IMO is that people who make CSV place no limits on what range of characters is stored in the tables. Certain characters can safely be removed. In most cases the input is still comprehensible without commas. Commas can be deleted, freeing up their use exclusively as record separators.
