java.nio.charset.UnsupportedCharsetException: cp65001

Hi,

I’m trying to install keycloak on my Win10 machine, running with a JDK 11.0.9 downloaded directly from the Oracle website.
When trying to execute .\kc.bat start-dev to try Keycloak out, I get the following error :

Do you know what may be causing this issue ?

Thank you
