Arabic Digits in RadRichTextEditor

[Emin Sadigov]

Hey Telerik Team,

I'm working with the RadRichTextEditor in WPF and ran into a little issue. When I switch my keyboard to Arabic, I was expecting to see Arabic digits (٠١٢٣٤٥), but instead, it still shows the standard Western numbers.

Is there a way to enable Arabic digits when typing in Arabic? I’ve looked around but haven’t had much luck so far. If there's a setting or a workaround that could help, I’d really appreciate any pointers!

using System.Globalization;

Console.OutputEncoding = System.Text.Encoding.UTF8;

CultureInfo arabicCulture = new CultureInfo("ar-AE");
arabicCulture.NumberFormat.DigitSubstitution = DigitShapes.NativeNational;
arabicCulture.NumberFormat.NativeDigits = ["٠", "١", "٢", "٣", "٤", "٥", "٦", "٧", "٨", "٩"];
//arabicCulture.CultureTypes = CultureTypes.
Thread.CurrentThread.CurrentCulture = arabicCulture;
Thread.CurrentThread.CurrentUICulture = arabicCulture;


int number = 12345;
Console.WriteLine(number.ToString(CultureInfo.CurrentCulture));

Hello Emin,

I tested the provided code snippet, however, the RadRichTextBox correctly displays the Arabic digits on my end. The following image showcases the produced result when pressing the digit keys on the keyboard:

The following code snippets showcase the setup on my end:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        CultureInfo arabicCulture = new CultureInfo("ar-AE");
        arabicCulture.NumberFormat.DigitSubstitution = DigitShapes.NativeNational;
        arabicCulture.NumberFormat.NativeDigits = ["٠", "١", "٢", "٣", "٤", "٥", "٦", "٧", "٨", "٩"];
        Thread.CurrentThread.CurrentCulture = arabicCulture;
        Thread.CurrentThread.CurrentUICulture = arabicCulture;

        InitializeComponent();
    }
}

<Grid>
    <telerik:RadRichTextBox x:Name="radRichTextBox" />
</Grid>

With this being said, I attached a sample project for you to test, so, could you give it a try and let me know how it goes?
