How to Handle Right-to-Left Text in Rust

Rust handles Right-to-Left (RTL) text automatically because its String type stores UTF-8 encoded text, which includes all Unicode characters used in RTL languages like Arabic and Hebrew. You do not need special code to store or process these characters; standard string methods work correctly on them.

fn main() {
    let rtl_text = "مرحبا"; // Arabic for "Hello"
    println!("{rtl_text}");
    println!("Length in bytes: {}", rtl_text.len());
    println!("Length in chars: {}", rtl_text.chars().count());
}

Note: While Rust handles the data correctly, visual rendering (mirroring text direction) is the responsibility of the terminal, browser, or GUI library you are using to display the output.

Rust stores text as a sequence of bytes that can represent any language in the world, including those written right-to-left. You don't need to do anything special to save or process this text; Rust just treats it as a standard string. The only thing you need to worry about is making sure the screen or app you are using to read the text knows how to display it in the correct direction.
