Is this treat with unicode can be managed?

Question

I found difference between compile with IDEs and Code Playground. Standard tools transform Unicode to ASCII characters and everything goes in common, but here we can see an exception. Can it be changed to work the same for better experience? Or at least, could explanation be added to FAQ?
Thank you for your answers

Answer 1

I wanted to post this as one of my "Java Special #xx" codes. I didn't because that doesn't work here in code playground.

Answer 2

@Krishna Teja Yeluripati
Is this a general problem for unicode signs? Or only jvm emulator?

Answer 3

It's a problem only with the code playground.

Answer 4

So any advice from the tutors?)
How better to do? Contact admins via feedback? Or just forget about this perk?
Is there necessary to make any notes about this? Someone have any other troubles using Unicode?
