Hi all

I have a case that i've been trying to do for a very long time.  
I have a string that contain #0D#0A character that i want to replace them with the string \r\n  
I've been trying to use gsub but it doesn't seem to be working at all.

Are there any solutions for what i'm trying to accomplish.

Thanks for your time.

Code:  
`mutate{ gsub => ["message", "#0D#0A", "\r\n"] }`

Data:

```auto
"original" => "something #0D#0Atest#0D#0A..."
"message" => "something \\r\\ntest\\r\\n...",

```

If you want single backslash, use ruby:

`	ruby { code => 'event.set("message", event.get("message").gsub("#0D#0A","\r\n"))' }`

```auto
"message" => "something \r\ntest\r\n..."

```
