+    .SYNOPSIS
+        Gets file encoding. Defaults to ASCII.
+
+    .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
