我错误地解码了utf8字符-šđžčć

Question

I have a word which contains some of these characters - šđžčć. When I take the first letter out of that word, I'll have a byte, when I convert that byte into string I'll get incorrectly decoded string. Can someone help me figure out how to decode properly the extracter letter. This is example code:

package main

import (
    "fmt"
)

func main() {
    word := "ŠKOLA"
    c := word[0]

    fmt.Println(word, string(c)) // ŠKOLA Å
}

Š is more than one byte. One method to index runes is to convert the string to []rune

c := []rune(word)[0]

You can also use the functions provided in the utf8 package, like utf8.DecodeRune and utf8.DecodeRuneInString to iterate over the individual codepoints in the utf8 string.

r, _ := utf8.DecodeRuneInString(word)
fmt.Println(word, string(r))
