Safe foldernames in SharePoint with PowerShell

Just a simple PowerShell function to make sure you only pass legal characters to (for instance) a foldername.

function safefoldername ([string] $name) {
    $chars = "#%&*:<>?/{|}"
    $chars.ToCharArray() | ForEach {
        $name = $name.Replace("$_","")
    }
    return $name
}
