Set the default en coding to UTF-8 in powershell. As seen in http://blogs.msdn.com/b/powershell/archive/2006/12/11/outputencoding-to-the-rescue.aspx

UTF8DefEncoding.ps1

$OutputEncoding = New-Object -typename System.Text.UTF8Encoding
[Console]::OutputEncoding = New-Object -typename System.Text.UTF8Encoding

"$OutputEncoding = [Console]::OutputEncoding = [Text.UTF8Encoding]::UTF8"
This works...

Add $env:LC_ALL='C.UTF-8' to your $profile.

👍

"$OutputEncoding = [Console]::OutputEncoding = [Text.UTF8Encoding]::UTF8" works for me.

I have tried:

• "$PSDefaultParameterValues = @{'Out-File:Encoding' = 'utf8'}" didn't work
• "$PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'" didn't work.

[Console]::OutputEncoding = [Text.UTF8Encoding]::UTF8

God bless your soul!

$PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'

worked for me for PowerShell 5.1, as per this doc

Ended up using $PSDefaultParameterValues['*:Encoding'] = 'utf8' to set utf-8 to "to change the default encoding for all cmdlets that have the Encoding parameter". Also put it in the $profile file for persistence.

You can also add [Console]::OutputEncoding = [Text.UTF8Encoding]::UTF8 to the start of your powershell profile script.

Notepad $profile
If the file doesn't exist, create one
add [Console]::OutputEncoding = [Text.UTF8Encoding]::UTF8 as the first line of the file`
save
restart powershell
