strings.Map 関数を使用して非 ASCII テキスト入力を ASCII に正規化する方法

<code class="go">package main

import (
    "fmt"
    "strings"
)

func main() {
    data := "Hello “Frank” or ‹François› as you like to be ‘called’"
    fmt.Printf("Original: %s\n", data)
    cleanedData := strings.Map(normalize, data)
    fmt.Printf("Cleaned: %s\n", cleanedData)
}

func normalize(in rune) rune {
    switch in {
    case '“', '‹', '”', '›':
        return '"'
    case '‘', '’':
        return '\''
    }
    return in
}</code>

Original: Hello “Frank” or ‹François› as you like to be ‘called’
Cleaned: Hello "Frank" or "François" as you like to be 'called'
