Rust는 문자열을 uft-8로 처리한다.
기본적으로
Vec<u8>로 처리
fn main() {
let my_str = "안녕하세요.";
for char in my_str.chars() {
let code_point = char as u32;
println!("문자 '{}': U+{:04X}", char, code_point);
}
// UTF-8 인코딩
let utf8_encoded = my_str.as_bytes();
println!("UTF-8 인코딩 결과: {:?}", utf8_encoded);
// UTF-16 인코딩
let utf16_encoded: Vec<u16> = my_str.encode_utf16().collect();
println!("UTF-16 인코딩 결과: {:?}", utf16_encoded);
// UTF-32 인코딩
let utf32_encoded: Vec<u32> = my_str.chars().map(|c| c as u32).collect();
println!("UTF-32 인코딩 결과: {:?}", utf32_encoded);
println!();
let my_str02 = "테스트";
println!("테스트 : {:?}", my_str02.as_bytes());
