I cannot print color escape codes to the terminal

Question

When I run this script:

fn main() {
    // \033[0;31m <- Red
    // \033[0m <- No Color
    println!("\033[0;31mSO\033[0m")
}

I expect to get

SO #in red letters

However, I get:

33[0;31mSO33[0m

When I ran similar script in Go or Python, I get the expected output. What is going on? What am I missing? How do fix this?

I am using:

$ rustc --version
rustc 1.3.0 (9a92aaf19 2015-09-15)
$ lsb_release -a

Answer 1

Rust 1.3.0 does not seem to support octal escape strings such as \033. Instead, you can use hexadecimal escape strings like \x1b.

fn main(){
  println!("\x1b[0;31mSO\x1b[0m")
}

Updated: This answer was intended that "you cannot use octal character such as \033, use hexadecimal character \x1b instead", but If you want to know about ANSI Escape code, maybe this gist is useful.
