Go で文字列を反転し、発音区別記号を組み合わせた Unicode を処理する方法は?

<code class="go">package main

import (
    "fmt"
    "os"
    "runtime"
    "unicode"
)

func main() {
    var stringsToReverse = []string{"Hello, World", "??⃠?", "??‍?????‍⚖️", "aͤoͧiͤ  š́ž́ʟ́", "H̙̖ell͔o̙̟͚͎̗̹̬ ̯W̖͝ǫ̬̞̜rḷ̦̣̪d̰̲̗͈"}
    for _, s := range stringsToReverse {
        fmt.Printf("Reverse '%s' => '%s'\n", s, ReverseString(s))
    }

    fmt.Printf("Memory usage: %d bytes\n", runtime.MemStats.Alloc)
    os.Exit(0)
}

// ReverseString reverses the characters in a string, handling Unicode combining diacritical marks
func ReverseString(s string) string {
    sv := []rune(s)
    cv := make([]rune, 0)
    rv := make([]rune, 0)

    for ix := len(sv) - 1; ix >= 0; ix-- {
        r := sv[ix]
        if unicode.In(r, combining) {
            cv = append(cv, r)
            fmt.Printf("Detect combining diacritical mark ' %c'\n", r)
        } else {
            rrv := make([]rune, 0, len(cv)+1)
            rrv = append(rrv, r)
            rrv = append(rrv, cv...)
            fmt.Printf("regular mark '%c' (with '%d' combining diacritical marks '%s') => '%s'\n", r, len(cv), string(cv), string(rrv))
            rv = append(rv, rrv...)
            cv = make([]rune, 0)
        }
    }

    return string(rv)
}</code>
