4 months ago PDFsharp does not (yet) support LTR languages, Japanese, Chinese, Korean, ...
Issue here is that the font does not contain 0xE0100 and PDFsharp did not handle this correctly. Beginning with 6.1.0-preview-2 a placeholder square will be drawn when requesting 0xE0100.
If IVS requires different handling, then this still must be added to PDFsharp. PDFsharp does not handle ligatures yet either. Thanks for your feedback.
Hi, I am using PDFsharp version 6.1.0 preview with .NET Framework 4.6.1. When I tried to write an IVS (Ideographic Variation Sequence) word using string target = char.ConvertFromUtf32(0x2D997) + char.ConvertFromUtf32(0xE0100); and called the DrawString function of PdfSharp.Drawing.XGraphics, it threw an IndexOutOfRangeException. Does PDFsharp support IVS?
