Kuidas on stringid rakendatud ja kuidas nad on seotud rune'idega Go keeles?

In the Go language, strings are represented by the string type, which is an immutable sequence of bytes, usually encoded in UTF-8. This means that a string is a sequence of bytes, not characters.

Runes (rune) are a type that represents a Unicode code point (int32). To work with Unicode characters in a string, the string is converted into a sequence of runes, which allows correct handling of multibyte characters.

Example:

s := "Привет"
for i, r := range s {
    fmt.Printf("%d: %c\n", i, r) // i — byte index, r — rune (character)
}

runes := []rune(s) // convert string to a sequence of runes
fmt.Println(runes[0]) // first character as a rune

Thus, in Go, strings are sequences of bytes, and runes are individual Unicode characters, which allows correct working with multilingual texts.
