[jira] [Updated] (ARROW-17970) [Ruby] Parsing escaped inner quotations incorrectly.

     [ https://issues.apache.org/jira/browse/ARROW-17970?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Salomons updated ARROW-17970:
------------------------------------
    Description: 
When using the CSVReader for a value with inner quotations escaped by backslashes the value is incorrectly parsed.

When I use
{code:java}
table = Arrow::MemoryMappedInputStream.open(file.path) do |input|
    Arrow::CSVReader.new(input, options).read
end{code}
On a row such as
{code:java}
"Some value", "Another \"value\" quotations", "Last value"{code}
It outputs 
{code:java}
Some value
Another value" quotations"
Last value{code}
When my expected output is
{code:java}
Some value
Another "value" quotations
Last value{code}
I've tried plenty of different options in different combinations, mainly the three below ones though.
{code:java}
options.quoted = true
options.double_quoted = false (tried with true)
options.escape_character = 92{code}
I assume this is a bug.
