/**
|
|
* Simple utilities for escaping/quoting/parsing CSV data.
|
|
*
|
|
* This only supports the default Excel-like encoding, in which fields containing any separators
|
|
* or quotes get quoted (using '"'), and quotes get doubled.
|
|
*
|
|
* Quoting is also applied when values contain leading or trailing whitespace, and on parsing,
|
|
* leading or trailing whitespace in unquoted values is trimmed, so that "," or ", " may be used
|
|
* as a separator.
|
|
*
|
|
* This is intended for copy-pasting multi-choice values, where plain comma-separated text is the
|
|
* most user-friendly, and CSV encoding is used to ensure we can handle arbitrary values.
