-Integrated the text-shaping algorithm. This change significantly improves the Unicode compatibility. Also, it extends support for more advanced languages (e.g. Arabic) that:
-1) Combine multiple text characters and display them as a single visual glyph.
-2) Are displayed in the right-to-left order. 
-
-Improved the exception message when SkiaSharp throws the TypeInitializationException. On some operating systems, SkiaSharp requires additional dependencies installed as nuget packages. This change should help developers determine how to choose and install them correctly. 
-
-Fixed: a rare case when the Row.AutoItem() does not correctly calculate the width of its content. 
-
-Fixed: the QuestPDF Previewer does not work with content-rich documents.

 QuestPDF is an open-source .NET library for PDF documents generation.
 
-It offers a layout engine designed with a full paging support in mind. The document consists of many simple elements (e.g. border, background, image, text, padding, table, grid etc.) that are composed together to create more complex structures. This way, as a developer, you can understand the behavior of every element and use them with full confidence. Additionally, the document and all its elements support paging functionality. For example, an element can be moved to the next page (if there is not enough space) or even be split between pages like table's rows. All of it done with predictable and discoverable Fluent API.
-
-## Installation
