Option liberal_parsing

Specifies the boolean value that determines whether CSV will attempt to parse input not conformant with RFC 4180, such as double quotes in unquoted fields.

Default value:

CSV::DEFAULT_OPTIONS.fetch(:liberal_parsing) # => false

For examples in this section:

str = 'is,this "three, or four",fields'

Without liberal_parsing:

# Raises CSV::MalformedCSVError (Illegal quoting in str 1.)
CSV.parse_line(str)

With liberal_parsing:

ary = CSV.parse_line(str, liberal_parsing: true)
ary # => ["is", "this \"three", " or four\"", "fields"]
