When outputting files, it is usually beneficial for characters that would cause trouble with formatting/syntax to be properly escaped. However, there are situations where suppressing this behavior is desirable.
Of particular importance for such a feature is in the outputting of JSON files. Currently, if a file is output as JSON it will always have quotations escaped if they occur within a field, regardless of whether this conforms to the JSON standard. There are a variety of current workaround for this, including pre-formatting all fields to look like JSON and then outputting as a \0 delimiter CSV, but in many cases there is no need to escape any characters when outputting a JSON.
A simple toggle--as was created for suppressing BOM in CSVs--to disable character escaping would make the creation of JSON objects simpler and reduce the amount of workarounds required to output proper JSON.
