<# .SYNOPSIS Gets file encoding. .DESCRIPTION The Get-FileEncoding function determines encoding by looking at Byte Order Mark (BOM). Based on port of C# code from http://www.west-wind.com/Weblog/posts/197245.aspx .EXAMPLE Get-ChildItem *.ps1 | select FullName, @{n='Encoding';e={Get-FileEncoding $_.FullName}} | where {$_.Encoding -ne 'ASCII'} This command gets ps1 files in current directory where encoding is not ASCII .EXAMPLE Get-ChildItem *.ps1 | select FullName, @{n='Encoding';e={Get-FileEncoding $_.FullName}} | where {$_.Encoding -ne 'ASCII'} | foreach {(get-content $_.FullName) | set-content $_.FullName -Encoding ASCII} Same as previous example but fixes encoding using set-content #> function Get-FileEncoding { [CmdletBinding()] Param ( [Parameter(Mandatory = $True, ValueFromPipelineByPropertyName = $True)] [string]$Path ) [byte[]]$byte = get-content -Encoding byte -ReadCount 4 -TotalCount 4 -Path $Path if ( $byte[0] -eq 0xef -and $byte[1] -eq 0xbb -and $byte[2] -eq 0xbf ) { Write-Output 'UTF8' } elseif ($byte[0] -eq 0xfe -and $byte[1] -eq 0xff) { Write-Output 'Unicode' } elseif ($byte[0] -eq 0 -and $byte[1] -eq 0 -and $byte[2] -eq 0xfe -and $byte[3] -eq 0xff) { Write-Output 'UTF32' } elseif ($byte[0] -eq 0x2b -and $byte[1] -eq 0x2f -and $byte[2] -eq 0x76) { Write-Output 'UTF7'} else { Write-Output 'ASCII' } }
