How to Reverse Strings in Go While Preserving the Order of Combining Diacritical Marks?

Reverse Strings in Go

Strings in Go are byte vectors rather than character sequences. This distinction poses challenges when attempting to reverse strings in the language. The following code snippet demonstrates the basic approach to inverting strings in Go:

<code class="go">import (
    "fmt"
    "rand"
    "time"
)

func invert() {
    var c = "A"
    var strs, aux string

    rand.Seed(time.Now().UnixNano())
    // Generate 5 strings with random characters of sizes 100, 200, 300, 400 and 500
    for i := 1; i <p>However, handling combining characters, unicode characters meant to modify others, introduces complexity to the reversal process. To address this, consider the approach proposed by Andrew Sellers, which involves:</p>
<ol>
<li>Listing Unicode block ranges for combining diacritical marks (CDM)</li>
<li>Reading the initial string rune after rune</li>
<li>Identifying and preserving CDM order, and combining them with regular runes before adding them to the reversed array</li>
</ol>
<p>This approach preserves the proper order of CDM characters and ensures accurate reversal of complex strings containing emojis and other combining elements.</p></code>
