Problem with the locale of binaries built on GitHub Actions

[banacorn]

If the source contains Unicode symbols like ⊤ in the example below:

module A where

data ⊤ : Set where 
  tt : {!   !}

The language server would crash with the following log output:

Also, it seems like the are some concurrent interleaving problem with the logger.

probably related to haskell/haskell-language-server#601
