Escape Option

An escape delimiter is simply a sequence that is recognized and ignored during parsing. Its purpose is to allow the use of escape sequences to embed byte sequences in data that would otherwise be seen as delimiter occurrences.

For example, if there is a normal delimiter “+” at a given level, and we define an escape delimiter “\+” as shown in the following figure, then aaa+b\+c+ddd will parse as three fields: aaa, b\+c, and ddd. If the escape delimiter were not defined, the sequence would then parse as four fields: aaa, b\, c, and ddd.

If there is only an escape delimiter on a given level, however, it presents a no delimiter defined situation for delim and array nodes.
