Smiley with drooping eyebrows is sad and crying. A tear drop is running down the cheek. A picture of misery. Not so much general sadness, but rather pain over one thing. It still hurts to remember a certain event.
The crying face emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the smileys and emotions
category. Because the crying face emoji has been around for quite some time, it should display correctly in the majority of operating systems.
