Problem

The RadPdfProcessing version for .NET standard does not look for the fonts on the operating system and falls back to the standard fonts.

Solution

Manually register the fonts in your application.

csharp

    var fontData = File.ReadAllBytes(@"..\..\..\Roboto-Bold.TTF");
    FontsRepository.RegisterFont(new FontFamily("Roboto"), FontStyles.Normal, FontWeights.Bold, fontData);

    Block block = new Block();

    block.InsertText(new FontFamily("Roboto"), FontStyles.Normal, FontWeights.Bold, "Text");
    editor.Position.Translate(100, 100);
    editor.DrawBlock(block);
