Use Rust's built-in UTF-8 String type and the .chars() iterator to safely handle non-ASCII text.
Use the standard String type, which stores UTF-8 encoded text by default, to handle non-ASCII characters safely.
fn main() {
let hello = String::from("Hello, δΈη!");
println!("{hello}");
}
When iterating, use .chars() to get Unicode scalar values instead of bytes to avoid splitting characters incorrectly.
Rust strings automatically handle international text like emojis or Chinese characters using a standard called UTF-8. You don't need special tools; just use the normal String type and iterate with .chars() to read each symbol correctly. Think of it like a universal translator that works for every language out of the box.
