Here we use wsltty as example. The same options can be applied to mintty too.

1. Download wsltty
2. Open properties of WSL Terminal shortcut, add -o LigaturesSupport=1 -o Ligatures=2 options. It should looks like below

C:\Users\<username>\AppData\Local\wsltty\bin\mintty.exe -o LigaturesSupport=1 -o Ligatures=2 --WSL= --configdir="C:\Users\<username>\AppData\Roaming\wsltty" -~  -
