How to change the default encoding to UTF-8 in Windows Terminal App(UWP)

I'm using the files that are encoded with UTF-8 but the default encoding for me is EUC-KR(chcp 949), I want to know the way that adapts the UTF-8 as the default encoding of my terminal(automatically when the terminal starts). I'm using PowerShell core 7.0.2. I don't want to type "chcp 65001" anymore when I start it.
