+Set this option to make sure `cfonts` used `CRLF` (`\r\n`) over the default `LF` (`\n`) [line breaks](https://en.wikipedia.org/wiki/Newline).  
+This could be useful for terminal raw modes or on older windows machines.

+```rust
+use crossterm::terminal;
+use std::io::Write;
+use cfonts;
+
+fn main() -> std::io::Result<()> {
+	terminal::enable_raw_mode()?;
+
+	cfonts::say(cfonts::Options {
+		text: String::from("Hello|world"),

+	terminal::disable_raw_mode()?;
