In a WPF project targeting .NET 6, the following code snippet results in an error:

        public MainWindow()
        {
            InitializeComponent();

            Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider provider = new Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider();
            RadFlowDocument document = provider.Import("<html><body><h1>My First Heading</h1><p>My first paragraph.</p></body></html>");
        }
System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Text.Encoding.CodePages, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.'

Workaround: edit the .csproj file and include the required package reference:

	<ItemGroup>
		<PackageReference Include="Telerik.Windows.Documents.Flow" Version="2024.2.426" />
		<PackageReference Include="System.Text.Encoding.CodePages" Version="7.0.0" />
	</ItemGroup>

(DIPs) is a unit type used in RadWordsProcessing when setting the FontSize of a Run. If you load a document with font size in WordPad set to 20 points and load it to RadFlowDocument, its value is converted by using the following method. If the RTF content stored from WordPad is saved to HTML format with WordPad, the font size is preserved with the same unit: style='font-size:20.0pt;'. We should add the option to control the font size unit when exporting to HTML format.
