Smileys, also known as “emoticons,” are glyphs used to convey emotions in your writing. They are a great way to brighten up posts.

By default, WordPress automatically converts text smileys to graphic images. When you type 😉 in your post you see when you preview or publish your post.

Select Settings -> Writing
In the Formatting section, uncheck the box for “Convert emoticons like 🙂 and 😛 to graphics on display“

Turning off emoticons means that when you type 😉 in a post you will see 😉 when you preview or publish your post. So it doesn’t stop you from using emoticons as plain text.
