+## Fallback Symbols based on script type
+
+The following code example demonstrates how a user can add fallback fonts based on the script types, which DocIO considers internally when converting a Word document to PDF.

+{% tabs %}
+
+{% highlight c# tabtitle="C# [Cross-platform]" %}
+//Opens the file as stream.

+    {
+        //Adds fallback font for basic symbols like bullet characters.
+        wordDocument.FontSettings.FallbackFonts.Add(ScriptType.Symbols, "Segoe UI Symbol, Arial Unicode MS");
+        //Adds fallback font for mathematics symbols.
+        wordDocument.FontSettings.FallbackFonts.Add(ScriptType.Mathematics, "Cambria Math, Noto Sans Math, Segoe UI Symbol, Arial Unicode MS");
+        //Adds fallback font for emojis.

 ## Fallback fonts for range of Unicode text
