Customer can't raise an issue when he adds an emoji in his text

Actual behaviour

When a customer user JIRA Service Desk from a mobile device or a Mac he will tend to use an emoji like :poop: when something goes wrong or :thumbsup: when his issue is fixed really fast.

When he do this, he can't raise his issue or add comment. See attachted file.

Expected behaviour

There are different ways to fix:

• Make the error message more user friendly so the customer knows what is the problem.
• Ignore / cut off the emoji from the input field and let the issue create without the emoji
• Make emoji availible (https://github.com/arvida/emoji-cheat-sheet.com)

Notes

I read this KB https://confluence.atlassian.com/x/0w6gGQ with PostgreSQL as Workaround. Because i use MySQL i can't try if JSD will work with that or not.
