I'm having an issue on a React Native / WP API mobile app.
I want to use WP Comments via WP API to post comments on news.
Everything works fine, except the emojis part. I can POST request with text, emoticons (smileys), but when I try to post a comment with emojis (let's say the comment content is " super comment: " - iOs emojis), my request returns an error: rest_comment_failed_create, with status 500.
I did the same directly into WP Admin (added a comment with this content: it creates a new comment with an empty content).
I guess emojis are not implemented right now on my WP installation, but is there a way to do that?
