What do you mean? What does inserting emojis have to do with it? The fact is that after inserting emojis and saving the article, they turn into 'question marks' = not supported by Freshworks by default. The two answers above are useless information. We need to push the Freshworks to properly implement emojis in 2024 - that is the point!
To give a clear example, I've attached a GIF showing the issue. As you can see, when I insert an emoji and save the article, it turns into a question mark. This demonstrates that Freshworks does not support emojis by default.
