Eclipse doesn't allow the rendering of greek characters in the console

If I try to output any greek character αΑβΒγΓδΔεΕζΖηΗθΘιΙκΚλΛμΜνΝξΞοΟπΠρΡςΣτΤυΥφΦχΧψΨωΩ to the Eclipse console (sysout), it gets replaced by a questionmark ?.

• Im using Eclipse 2022-03
• I have enabled UTF-8 in each of the following settings:
  • Run As -> Run configurations -> Common -> Encoding
  • Preferences -> General -> Content Types -> Text
  • Preferences -> Workspace -> Text file encoding
• Console Font: Consolas (default / works in the text-editor)
• Operating System: Windows 11

Also: When I try to render äöüÄÖÜß with UTF-8, it gives the �-character. (This can be fixed by enabling ISO-859-1 under Run As -> Run configurations -> Common -> Encoding)
