Functions

func Add

func Add(val string) string

Add adds emoji variation selectors to all emojis that have multiple forms in the given string.

This will remove all variation selectors first to make sure it doesn't add duplicates.

Example

package main

import (
	"fmt"
	"strconv"

	"maunium.net/go/mautrix/util/variationselector"
)

func main() {
	fmt.Println(strconv.QuoteToASCII(variationselector.Add("\U0001f44d")))           // thumbs up (needs selector)
	fmt.Println(strconv.QuoteToASCII(variationselector.Add("\U0001f44d\ufe0f")))     // thumbs up with variation selector (stays as-is)
	fmt.Println(strconv.QuoteToASCII(variationselector.Add("\U0001f44d\U0001F3FD"))) // thumbs up with skin tone (shouldn't get selector)
	fmt.Println(strconv.QuoteToASCII(variationselector.Add("\U0001f914")))           // thinking face (shouldn't get selector)
}

Output:

"\U0001f44d\ufe0f"
