Thank you for reporting the issue.

So far, your case looks to be a typical symptom when the application or its UI framework does not properly handle Emoji characters. In such a case, basically the application or its UI framework needs to be fixed.

Sorry for not being able to help. Hope you find a good workaround or solution.
