When CJK text (Chinese, Korean, Japanes) is copied from WordPad and paste into RadRichTextBox text, the characters are imported incorrectly (as '?' and as different characters). The same applies if WordPad document containing CJK is imported from RTF. 

The problem is related to the specified \fcharset134 RTF tag, which is not properly interpreted.

When you have more than one RadRichTextEditor controls on the form and you have selected text in both of theme, only the focused RadRichTextEditor should show the selection.

To reproduce:
 - Add a table where the width is set to 100%
 - Import the table and the export it:
private void radButton_Click(object sender, RoutedEventArgs e)
{
    var provider = new HtmlFormatProvider();
    string text = File.ReadAllText(@"..\..\default.html");
    rtb1.Document = provider.Import(text);
}

private void radButton1_Click(object sender, RoutedEventArgs e)
{
    var provider = new HtmlFormatProvider();
    provider.ExportSettings.StylesExportMode = StylesExportMode.Inline;
    string content = provider.Export(rtb1.Document);
    File.WriteAllText(@"D:\test1.html", content);
}

Workaround:
 Leave the export mode intact.

Pressing Tab/Shift+Tab when caret position is at the beginning of a paragraph should change current paragraph FirstLineIndent instead of LeftIndent.

First line indent should be changed to Document.DefaultTabWidth step.

Workaround:
private void RadRichTextEditor1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyData != Keys.Tab)
    {
        return;
    }

    this.radRichTextEditor1.Insert("\t");
    e.SuppressKeyPress = true;
    e.Handled = true;
}

Add only a RichTextEditorRibbonBar without any other control on the form. If you run the application you will notice that it loads more than one second. We should investigate if it is possible and how to improve the initialization time.

There is an issue with the way the editor decides what width to render a table.

The example I have encountered is in an HTML email from Outlook that contained a table. Whatever way Outlook composes the HTML, it adds a width attribute and a style attribute to the table's opening tag:

<table width="0" style="width: 500px;">

In this situation, the inline style should take precedence over the width attribute (the width attribute is actually deprecated as of HTML5). This is how all common browsers behave.

You can see in the attached 1_browser.png that Chrome correctly renders the table at 500px;

However the RadRichtextEditor component incorrectly renders the table at width 0 as shown in attached 2_RadRichtextEditor.png, ignoring the width specified in the style attribute.

Curiously, other CSS rules in the style attribute are correctly interpreted.
For example:

<table width="0" style="width: 500px;font-weight:bold;">

will display a table of zero width with bold text in the RadRichTextEditor.

Thanks guys!

Workaround: To clear a given property, basing on some logic which determines if it should be cleared. For example
this.radRichTextEditor1.CommandExecuting += (s, e) =>
{
    if (e.Command is ChangeStyleNameCommand)
    {
        var style = this.radRichTextEditor1.Document.StyleRepository.GetValueOrNull(e.CommandParameter.ToString());
        if (style.Type == Telerik.WinForms.Documents.Model.Styles.StyleType.Paragraph)
        {
            Paragraph paragraph = this.radRichTextEditor1.Document.CaretPosition.GetCurrentParagraphBox().AssociatedParagraph;
            foreach (Span span in paragraph.EnumerateChildrenOfType<Span>())
            {
                span.ClearValue(Span.FontFamilyProperty);
                span.ClearValue(Span.FontSizeProperty);
            }
        }
    }
};

Workaround: Set the next style property for all types except the Paragraph to an empty string
foreach (var style in this.radRichTextBox.Document.StyleRepository)
{
    if (style.Type!=Telerik.Windows.Documents.Model.Styles.StyleType.Paragraph && !string.IsNullOrEmpty(style.NextStyleName))
    {
        style.NextStyleName = string.Empty;
    }
}

1. Create a document containing a style with NextStyleName:

           StyleDefinition myStyle = new StyleDefinition();
            myStyle.Type = StyleType.Table;
            myStyle.DisplayName = "My Style";
            myStyle.Name = "myStyle";
            myStyle.NextStyleName = RadDocumentDefaultStyles.HyperlinkStyleName;

            this.radRichTextBox.Document.StyleRepository.Add(myStyle);

2. Add several paragraphs and select some of them (ensure there is one using our custom style).

3. Create a DocumentFragment using the selection's CopySelectedDocumentElements

4. Convert the fragment to RadDocument and try to export it

Observed: When exporting to DOCX and XAML, the style is missing. Exporting to RTF causes KeyNotFoundException.

Expected: The style should be preserved in the exported document

Workaround: After creating the document from the fragment, ensure all needed styles are copied and available.
