What kind of emojis are you looking to support? Do you know the Unicode range? Try this one – Maurya

Answer 1

You seem to want to match a specific set of emojis.

Use

package main

import (
    "fmt"
    "regexp"
)

func main() {
    var emojiRx = regexp.MustCompile(`[\x{1F600}-\x{1F6FF}|[\x{2600}-\x{26FF}]`)
    var s = emojiRx.ReplaceAllString("Thats a nice joke 😆😆😆 😛", `[e]`)
    fmt.Println(s)    
}

See the Go demo.

Note that:

• [\x{1F600}-\x{1F64F}] - matches smilies
• [\x{1F680}-\x{1F6FF}] - matches transport emojis, etc.

A regex to match all emojis listed in the Emoji 14.0 Standard you can use

emojiRx :=

See the RE2 regex demo, now it matches all the current 4702 emojis.

Note this doesn't handle all emojis. E.g. 👏 – Opportuna

@BenJohnson I know it now, I did not 5 years ago. – Maurya

Answer 2

My other complete answer was deleted, accidentally I assume.

This is how to match v14 (and below) IEmoji characters using regex with Go.
It is a UTF-8/32 regex.
This regex is 3k in size and matches a minimum of 120,000 IEmoji's per second.
There is no regex that is faster.
