+## Description
+
+When generating PDF files using [RadWordsProcessing]({%slug radwordsprocessing-overview%}) from HTML or DOCX templates, specific content may be **missing** in the output due to the fonts used in the document. This occurs because the .NET Standard version of [RadPdfProcessing]({%slug radpdfprocessing-overview%}) does not have a default mechanism to read fonts. To resolve this issue, the font data must be provided explicitly using the **FixedExtensibilityManager** and a custom implementation of the [FontsProviderBase]({%slug pdfprocessing-implement-fontsprovider%}) class.
+
+This knowledge base article also answers the following questions:
+- Why is some text missing in RadWordsProcessing-generated PDFs?
+- How do I add support for custom fonts in RadPdfProcessing?
+- How can I fix missing content in exported PDF files?
+
+## Solution
+
+To ensure that custom fonts are correctly embedded in the PDF files:
+
+1. **Implement a FontsProvider**:
+   Create a custom class that inherits from `FontsProviderBase` and override the `GetFontData` method to provide the font data for the required fonts.
+
+   Example implementation:
+   ```csharp
+   internal class FontsProvider : Telerik.Windows.Documents.Extensibility.FontsProviderBase
+   {
+       private string fontFolder = Environment.GetFolderPath(Environment.SpecialFolder.Fonts);
+
+       public override byte[] GetFontData(Telerik.Windows.Documents.Core.Fonts.FontProperties fontProperties)
+       {
+           string fontFamilyName = fontProperties.FontFamilyName;
+           bool isBold = fontProperties.FontWeight == Telerik.Documents.Core.Fonts.FontWeights.Bold;
+           if (fontFamilyName == "David")
+           {
+               fontFolder = @"..\..\..\";
+               var fontData = this.GetFontDataFromFontFolder("David.ttf");
+               fontFolder = Environment.GetFolderPath(Environment.SpecialFolder.Fonts);
+               return fontData;
+           }
+
+           Debug.WriteLine($"Font not found: {fontFamilyName} (Bold: {isBold})");
+           return null;
+       }
+
+       private byte[] GetFontDataFromFontFolder(string fontFileName)
+       {
+           using (FileStream fileStream = File.OpenRead(this.fontFolder + "\\" + fontFileName))
+           {
+               using (MemoryStream memoryStream = new MemoryStream())
+               {
+                   fileStream.CopyTo(memoryStream);
+                   return memoryStream.ToArray();
+               }
+           }
+       }
+   }
+   ```
+
+2. **Set the FontsProvider in FixedExtensibilityManager**:
+   Assign the custom FontsProvider implementation to the `FontsProvider` property of `FixedExtensibilityManager`.
+
+   ```csharp
+   Telerik.Windows.Documents.Extensibility.FontsProviderBase fontsProvider = new FontsProvider();
+   Telerik.Windows.Documents.Extensibility.FixedExtensibilityManager.FontsProvider = fontsProvider;
+   ```
+
+3. **Ensure Font Availability**:
+   Download and include all necessary font files (e.g., `David.ttf`) used in your document. Place them in an accessible location relative to your application.
+
+4. **Rebuild and Run**:
+   Integrate the FontsProvider implementation into your application, rebuild, and test the PDF generation process. The previously missing content should now appear in the exported PDF files.
