UTF8 Script in PowerShell outputs incorrect characters

Changing the encoding of the script to UTF-8 with BOM solved the issue.

I was using SublimeText with the EncodingHelper plugin to control the character-set of the script. It was set correctly to UTF8.

I changed the encoding of the script in SublimeText to "UTF-8 with BOM" and the output was shown correctly.

I created the same script with Notepad++, which defaults to "UTF-8 with BOM", and the string was shown correctly in the console.

I changed the encoding of the script in Notepad++ to "UTF-8 without BOM" and it was shown incorrectly.

It seems PowerShell cannot guess correctly the encoding of UTF-8 files with no BOM.

In my case the problem was caused by creating a new PowerShell script with Visual Studio Code which has the default encoding of UTF-8 without BOM. Set the encoding to "Windows 1252" solved the problem.

It seems that PowerShell can't handle UTF-8 without BOM, it needs "Windows 1252" or "UTF8 with BOM" encodings.
