What I want:
String x = "" ;
What I get in Apple TextEdit 1.16 text editor app when clicking from the macOS "Show Emojis & Symbols" floating windoid:
String x = "" ;
Problem 1
What I get in IntelliJ 2021.2.2 code editor when clicking from the macOS "Show Emojis & Symbols" floating windoid:
String x = "ð" ;
Update: This appears to be a currently known bug. See issue page IDEA-278540 Emoji in OSX are rendered as another unicode, as noted in Answer by Konstantin Annikov.
Problem 2
What I get in IntelliJ 2021.2.2 code editor when pasting that character copied from TextEdit app:
String x = "\uD83D\uDE37" ;
Presumably the issue revolves around Unicode characters outside the Basic Multilingual Plane.
➯ Is there any way to make the IntelliJ code editor accept such characters directly, without escaping?
