Issue with unichar

Hi

I'm having a really weird issue when i try to return a unichar character from an if-function or a switch.
I recreated the problem in a new powerbi report.

I want to return ✅ when the value equals 1, and ❌ when it doesn't.
So i tried this first, which seems to be working fine:


When i substitute blank by the unichar code for ❌, it doesn't work anymore:


Neither does switch:


Did anybody else run in to this problem before?
