| Instance | Output |
|---|---|
| “John”s Home” | “John”s Home” |
Deal with Line Breaks
Line breaks needs to be handled as subject separators. Use the mixture of a carriage return (CR) and a line feed (LF) to point a brand new line.
| Instance | Output |
|---|---|
| “John Doe” |
“JohnrnDoe” |
Use Escaping Characters
