Emojis sent through the Facebook API are not displayed correctly on Facebook.

This functionality used to work, but now, instead of emojis, the symbols “?” are displayed. I tried using UNICODE, HTML code and shortcode.

The problem can be reproduced in the Graph API Explorer.

For the test I used the following steps.

1. I took a Facebook profile ID.

GET /v20.0/me?fields=id,name

1. I created a video broadcast.

POST /v20.0/<USER_ID>/live_videos status="LIVE_NOW" title="Front 😝" description="Front 😝" 

1. After I started the broadcasting the Facebook post become visible.

2. After that, I made a request, using the broadcast ID, to receive the stream link.

The streaming link format as follows:

rtmps://live-api-s.facebook.com:443/rtmp/FB-1013749643592269-0-AbzJB6nb_Z183JwA,

To get the streaming link I made the following request:

GET /v20.0/<LIVE_VIDEO_ID>

1. I started a broadcast in "OBS Studio" with that streaming link.

2. I ended up checking the post on Facebook.
