I am attempting to create a new File Reader Service. Under the "Acceptable delimiters" button on the page, there are 33 different non-displayable character, delimiter options. I am familiar with several of them, but many of them I am not. I am seeking a single reference to define each of the 33 listed there. Example, what does a "Bell" delimiter look like, what does a "Data Link Escape" delimiter look like, etc.
