A comprehensive reference covering string types across multiple programming languages including Rust, C, C++, Go, Zig, Java, C#, Python, Swift, Pascal, and Haskell. For each language, the post explains the internal representation, mutability, growability, null-termination behavior, and unicode compliance of each string type. Rust's String, &str, OsString, and CString families are covered in depth, as are Zig's many byte-slice variants and Pascal's compiler-directive-dependent string types.
