Hey, it has json ld scripts:
{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Streamed executable output prints Ansi Escaping in Write-* Commandlets","articleBody":"### Prerequisites\r\n\r\n- [X] Write a descriptive title.\r\n- [X] Make sure you are able to repro it on the [latest released version](https://github.com/PowerShell/PowerShell/releases)\r\n- [X] Search the existing issues.\r\n- [X] Refer to the [FAQ](https://github.com/PowerShell/PowerShell/blob/master/docs/FAQ.md).\r\n- [X] Refer to [Differences between Windows PowerShell 5.1 and PowerShell](https://docs.microsoft.com/powershell/scripting/whats-new/differences-from-windows-powershell).\r\n\r\n### Steps to reproduce\r\n\r\nWhen piping input of an application to an Commandlet like Write-Error the written content contains the ansi escaping signs.\r\nFor example the command:\r\n```ps1\r\ndotnet --version | Write-Verbose -Verbose\r\n```\r\n\r\n### Expected behavior\r\n\r\nPrinting the following output in yellow:\r\n```console\r\nVERBOSE: 7.0.100\r\n```\r\n\r\n\r\n### Actual behavior\r\n\r\nThe following Text is printed colorless:\r\n```console\r\n\u001B[33;1mVERBOSE: 7.0.100\u001B[0m\r\n```\r\n\r\n\r\n### Error details\r\n\r\nIf the output is intercepted with Out-String the output seems to work correctly unless the Parameter -Stream is used. Seems like the Encoding is only broken when the text is returned as a stream down the pipline instead of at the end of the command.\r\n\r\nFor some very odd reason after I type an incorrect parameter like this:\r\n```ps1\r\ndotnet --version | Write-Verbose -u # -u does not exist\r\n```\r\nThe error-message is again displayed with ansi escape signs, but afterwards everything works as expected when I use the previous command again.\r\n\r\n### Environment data\r\n\r\n```powershell\r\nName                           Value\r\n----                           -----\r\nPSVersion                      7.3.0\r\nPSEdition                      Core\r\nGitCommitId                    7.3.0\r\nOS                             Microsoft Windows 10.0.19044\r\nPlatform                       Win32NT\r\nPSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}\r\nPSRemotingProtocolVersion      2.3\r\nSerializationVersion           1.1.0.1\r\nWSManStackVersion              3.0\r\n```\r\n\r\n\r\n### Visuals\r\n\r\n![image](https://user-images.githubusercontent.com/36636591/207059669-d2fd8f3f-fd19-44b7-8fa8-4a6613508768.png)\r\n","author":{"url":"https://github.com/Herrmel","@type":"Person","name":"Herrmel"},"datePublished":"2022-12-12T13:43:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/18771/PowerShell/issues/18771"}
