Describe your project (alternative: link to the project): https://github.com/ishiy1993/hls-debug-20210102

Contents of hie.yaml:

cradle:
  stack:
    - path: "./src/Main.hs"
      component: "hls-debug:exe:hls-debug"

    - path: "./src/Lib.hs"
      component: "hls-debug:exe:hls-debug"

Steps to reproduce

git clone git@github.com:ishiy1993/hls-debug-20210102.git
cd hls-debug-20210102
stack build                                          # no error
haskell-language-server-wrapper .    # type check error on src/Main.hs

I use Arch Linux.
The error may not occur on Mac.

Expected behaviour

no error with hls.

Actual behaviour

type check error on src/Main.hs

Severity: DsError
Message:
  • Exception when trying to run compile-time code:
  greeting.txt: hGetContents: invalid argument (invalid byte sequence)
  Code: embedFile "greeting.txt"
  • In the untyped splice: $(embedFile "greeting.txt")

The error comes from reading a file which includes Japanese with Template Haskell.

Same problem with a compile-time error. Any workaround with this problem?
