"Enclosure" attribute in Split fields plugin

What is the use of “Enclosure” attribute in Split fields plugin?

Hi Mayur,
Enclosure attribute is used to specify the field enclosure. Delimiter within pair of enclosure is ignored.

For example if we have input string- Madhavi “Kimaya Bade” shruti .
We split this string by delimiter space and give enclosure as " then space within enclosure would be ignored while splitting. Final field’s data would be
2)Kimaya Bade
