I am using twitter-text library in newest version for counting characters in the posting tweet function on my website. But there is a problem with mechanic Emoji(🧑🔧 ) which is formed by combining 1 [ZWJ zero width joiner] and 2 individual Emoji (person wearing blue overalls and holding a wrench). And in my website, It is counted 5 characters but in Twitter, it just has 2 character as a normal emoji. I don’t know why. Can someone help me?
