CSV encode double-escapes escape codes like CR

[karmajunkie]

When encoding a line which contains a field with an embedded escape code, CSV escapes the backslash, so the output contains \r\n instead of a CRLF. This is an issue with double-quoted fields which are allowed to have CRLF's embedded. See below:

iex(9)> IO.puts "foo\r\nbar"
foo
bar
:ok
iex(10)> [["foo\r\nbar", "foo", "bar"]] |> CSV.encode |> Enum.to_list
["\"foo\\r\\nbar\",foo,bar\r\n"]

I can work around it by regex removing the escaped backslash, but unless I'm missing something this is incorrect behavior.

Thanks for raising this, will have a look at a fix soon.

Am having exactly the same issue and my temporary fix is something like String.replace("\\n", "\n").

Hey all, this is fixed in 2.4.1 - feel free to reopen if issues persist.
