How can you determine the number of characters in a Cyrillic string?

In Go, strings are sequences of bytes, and Unicode characters (including Cyrillic) can occupy multiple bytes. To determine the number of characters (runes) in a Cyrillic string, you need to convert the string into a slice of runes and take its length:

s := "Привет"
runes := []rune(s)
count := len(runes)
fmt.Println(count) // Will output 6

This way, we correctly count the characters themselves, not the bytes.
