To clear the mystery, I learnt about the “String” window in IDA (View - Open subviews - Strings). There, right click and choose “Setup…”, and in there you can choose to display “Unicode C-style (16 bits)” strings as well. With Ctrl + F afterwards, we can search for it in the String window and identify it.
