@SteveL-MSFT Cpuld you please comment the issue?

[onriv]

@iSazonov are there any settings in my environment wrong? Btw, I run chcp 65001 in the profile

[mklement0]

@onriv, chcp 65001 from inside PowerShell isn't effective, because .NET caches the value of [Console]::OutputEncoding, which is what matters with respect to how PowerShell decodes stdout output from external programs.

You must set the latter directly:

[Console]::OutputEncoding = [System.Text.UTF8Encoding]::new($false)

See #7233 for details, which requests that UTF-8 be made the default (consistently; $OutputEncoding has fortunately already been switched to UTF-8).

[iSazonov]

@mklement0 The issue is on Windows where curl is cmdlet alias.

[mklement0]

@iSazonov, no, it is only an alias in _Windows PowerShell_; the alias was removed in PowerShell Core.

[mklement0]

P.S., the only reason it worked in 6.x was a _bug_ that caused [Console]::OutputEncoding to be ignored and UTF-8 to always be used - see #10789

[onriv]

@mklement0 I didnt know that chcp not working in powershell and didnt know there is a bug in PS6 too. Now I tried setting [Console]::OutputEncoding = [System.Text.UTF8Encoding]::new($false) in
PS7 and it works now. Thank you very much. I will check the docs you mentioned later.

[iSazonov]

I think can track this in #10789

[onriv]

Since My problem solved and there are enough informations to be referred. I closed the issue. Thank you very much
