Rules to follow when using ASCII characters.
You may use almost any ASCII character(s) that you want for each of these purposes; however, follow the rules listed below:
The set of characters for one purpose should not overlap the set of characters for any other purpose. For example, you should not use the same character as both a field separator and a line continuation character.
Do not use the newline character (or individual Line Feed or Carriage Return characters) as quote character(s), line continuation character(s), or field separator character(s).
As mentioned above, when you specify more than one character, EACH of the characters that you specify will be used for the specified purpose. You cannot create multi-character strings for any of these purposes; for example, if you specify "][" as the field separator characters, then each of the individual characters will be treated as field separators. In other words, the sequence "][" will be treated as 2 separate field separators.
There is currently no "escape character" that indicates that the next character should be treated as a literal rather than as a special character.
