Using PowerShell to write a file in UTF

Out-File seems to force the BOM when using UTF-8:

$MyFile = Get-Content $MyPath
$MyFile | Out-File -Encoding "UTF8" $MyPath

How can I write a file in UTF-8 with no BOM using PowerShell?

使用.NET的UTF8Encoding类并将$False传递给构造函数似乎可行：

$MyFile = Get-Content $MyPath
$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding $False
[System.IO.File]::WriteAllLines($MyPath, $MyFile, $Utf8NoBomEncoding)

---

The proper way as of now is to use a solution recommended by @Roman Kuzmin in comments to @M. Dudley answer:

[IO.File]::WriteAllLines($filename, $content)

(I've also shortened it a bit by stripping unnecessary System namespace clarification - it will be substituted automatically by default.)

I figured this wouldn't be UTF, but I just found a pretty simple solution that seems to work...

Get-Content path/to/file.ext | out-file -encoding ASCII targetFile.ext

For me this results in a utf-8 without bom file regardless of the source format.
