`web-ghc` fails to compile Haskell programs that use non-ANSI characters

[Pablo Lamela]

Is there an existing issue for this?

• I have searched the existing issues

Summary

web-ghc endpoint returns 500 error when provided with a Haskell program that uses non-ANSI characters

Steps to reproduce the behavior

1. Open https://playground.plutus.iohkdev.io/
2. Load Starter example
3. Modify the first comment to have a non-ANSI character.

-- Thís is a starter contract, based on the Game contract,

Note the accent in Thís
4. Click compile button

Actual Result

FailureResponse (Request {requestPath = (BaseUrl {baseUrlScheme = Http, baseUrlHost = "web-ghc-plutus-apps-prod.plutus.aws.iohkdev.io", baseUrlPort = 80, baseUrlPath = ""},"/runghc"), requestQueryString = fromList [], requestBody = Just ((),application/json;charset=utf-8), requestAccept = fromList [application/json;charset=utf-8,application/json], requestHeaders = fromList []), requestHttpVersion = HTTP/1.1, requestMethod = "POST"} (Response {responseStatusCode = Status {statusCode = 500, statusMessage = "Internal Server Error"}, responseHeaders = fromList [("Content-Type","text/plain; charset=utf-8"),("Date","Thu, 09 Dec 2021 16:11:09 GMT"),("Server","Warp/3.3.17"),("Transfer-Encoding","chunked")], responseHttpVersion = HTTP/1.1, responseBody = "Something went wrong"})

Expected Result

Compilation successful

Hey @palas thanks for the issue, we will investigate this and I will let you know what transpires.

@palas while we continue to investigate the reason the live site isn't handling this case, this seems to not be an issue in the current branch, as an interim fix I suggest running the playground locally using the steps in the README here.

I will then let you know when a fix goes live.

Thanks for reporting this!

Unfortunately, we are closing this issue as the plutus playground is no longer maintained by IOG. Thus, it was deleted from the plutus-apps repository.
