Can you post the code that doesn't work? C-style escaping in strings should work fine:

fn main() {
    let message = format!("hello\nworld!");
    println!("{}", message);
}

prints

hello
world!

@cbiffle yes this don't functioned:

format!("{} - \"{}\"","Test","Test with Double Quotes")

What do you want that to write? That code compiles, and it writes:

Test - "Test with Double Quotes"

@ExpHP and @cbiffle
Sorry my fault, i have outputted with debug and give the debugged variable to another function: format("{:?}","this must be quotes") and the function received and debugged string. My old fault but there in a strange condition, no println ("ahhh whats that for an string, An debug string"), therefore an format! ("äh why he puts espaced characters, when i use not an debug function.). Smile sorry:).
