Elegant Rust Intermediate (3) - Strings

Have you ever encountered a different string length with Korean text in Rust, or had code that slices a string panic? In this course, visual materials and runnable examples explain everything from the ownership relationship between `String` and &str to the difference between characters and bytes in UTF-8. You’ll practice creating, searching, splitting, and converting strings, as well as Unicode normalization, and learn the criteria for designing safe string APIs while reducing unnecessary copies.
