How To Define a Special Delimiter and Separator For Importing Key/Value Pairs

Problem

When I am importing a Key/Value pair and Control-A is a delimiter and Control-B is my separator, how do I specify these values to the Upload form?

If your delimiter and separator values are non-printable characters, specify them with \u followed by the unicode value, e.g., \u0001 for Control-A, \u0002 for Control-B. You can also define other delimiter characters like \t for tab.
