When exporting emoticons from the cloud editor (old editor and also available via new cloud editor) the standard emoticons available are not exported. These include:
For new emoticons provided via the new cloud editor experience we are aware these are not exported (instead the related text is exported) and we are tracking the issue internally. Atlassian have created their own issue for this behaviour and you can track this here: https://jira.atlassian.com/browse/CONFCLOUD-64431.
Steps to reproduce
Create a page using the new editor experience
Add the Smiley emoticon
Export the page
Expected result: The emoticon is exported
Actual result: A blank square is exported in Scroll PDF Exporter. A square with a red cross is exported with Scroll Word Exporter
