HI.
I am developing a C# winforms application.
In PDFsharp how i can print arabic text and how to print right to left.

I used below to code to print Arabic. It print Arabic characters but not in right to left order.

XPdfFontOptions options = new XPdfFontOptions(PdfFontEncoding.Unicode, PdfFontEmbedding.Always);
const string familyName1 = "Arial Unicode MS";
XFont fontB = new XFont(familyName1, 16, XFontStyle.Regular, options);

gfx.DrawString("فاتورة", fontB, XBrushes.MidnightBlue, new XRect(260, 90, 80, 15), XStringFormats.TopCenter)

Hi!

For some languages you can fake "right to left" by simply reversing the string.
With Arabic you also must make sure you use the correct glyph for beginnings, ends, and middle positions. Support for that is not (yet) included with PDFsharp.

Not my area of expertise. I cannot read Arabic.
There are four variants of "letter Beeh": isolated, initial, medial, final. PDFsharp does not (yet) select the correct variant based on the context.
I assume that your code must translate "Letter Beeh" found in the text with one of the for special variants, depending on the context.
