How to change the command prompt of WinGHCi?

Question

Windows 10 x64, Haskell

I created %appdata%\ghc\ghci.conf file and added into it the command for prompt changing:

:set prompt "\x03BB"

I see it was applied only for ghci.exe and ghci-8.0.1.exe, but WinGHCi prompt wasn't changed:

How can I fix it?

I think I have this problem: https://github.com/haskell/winghci/issues/7

Also:

The original author is no longer active with the project, but the code is still maintained. Please submit your pull requests here.

Therefore I will not learn this tool now.
