-The use of `Write-Host` is greatly discouraged unless in the use of commands with the `Show` verb.
-The `Show` verb explicitly means 'show on the screen, with no other possibilities'.
+The primary purpose of the `Write-Host` cmdlet is to produce display-only output in the host. For

+`Write-Host` uses the `ToString()` method to write the output. The particular result depends on the

 For a file encoded with a format other than ASCII, ensure Byte Order Mark (BOM) is present to ensure
 that any application consuming this file can interpret it correctly.
 
+You can use this rule to test any arbitrary text file, but the intent is to ensure that PowerShell
+scripts are saved with a BOM when using a Unicode encoding.
+
 ## How
 
-Ensure that the file is encoded with BOM present.
+For PowerShell commands that write to files, ensure that you set the encoding parameter to a value
+that produces a BOM. In PowerShell 7 and higher, the following values of the **Encoding** parameter
+produce a BOM:
+
+- `bigendianunicode`
+- `bigendianutf32`
+- `oem`
+- `unicode`
+- `utf32`
+- `utf8BOM`
+
+When you create a script file using a text editor, ensure that the editor is configured to save the
+file with a BOM. Consult the documentation for your text editor for instructions on how to save
+files with a BOM.
