PowerShell script to save as UTF-8 without a BOM

no-bom.ps1

gci . -recurse -filter *.ps* | % {
        $MyFile = gc $_.Fullname -raw
        $MyPath = $_.Fullname
        [System.IO.File]::WriteAllLines($MyPath, $MyFile, [System.Text.UTF8Encoding]($False))
}

use $MyFile = gc -raw -Encoding utf8 $_.Fullname instead ,and note if you don't properly set encoding via-Encoding utf8 for Get-Content,some characters would be garbled.
