Problem

This can happen when the characters cannot be found in a specific font. In this case, the RadPdfProcessing either falls back to another font or draws nothing.

Solution

To ensure that these symbols are available you need to embed a font that contains them to the document.

csharp

    var fontData = File.ReadAllBytes(@"..\\..\SegoeUI.ttf");
    FontsRepository.RegisterFont(new FontFamily("Segoe UI"), FontStyles.Normal, FontWeights.Normal, fontData);

    FontBase font;
    FontsRepository.TryCreateFont(new FontFamily("Segoe UI"), FontStyles.Normal, FontWeights.Normal, out font);
