PDFsharp does not (yet) support right-to-left languages.

You need to reverse the letters and then the whole string.
I needed it myself so its tested and working:

<pre><code> public static string ReverseString(this string str)
{
 StringBuilder sb = new StringBuilder();
 foreach (char c in str.Reverse())
 {
 sb.Append(c);
 }

 return sb.ToString();
}

 public static string RightToLeft(this string str)
{
 List&lt;string&gt; output = str.Split(' ').Select(s =&gt; s.Any(c =&gt; c &gt;= 1424 &amp;&amp; c &lt;= 1535) ? s.ReverseString() : s).ToList();
 output.Reverse();
 return string.Join(" ", output.ToArray());
}

 private void DrawStringBoxRightToLeft(XGraphics gfx, string text, XFont font, XBrush brush, XRect rect)
{
 List&lt;string&gt; words = text.Split(' ').ToList();
 List&lt;string&gt; sentences = new List&lt;string&gt;();

 while (words.Any())
 {
 while (gfx.MeasureString(string.Join(" ", sentences), font).Width &lt; rect.Width &amp;&amp; words.Any())
 {
 string s = words[0];
 sentences.Add(s);
 words.RemoveAt(0);
 }

 gfx.DrawString(string.Join(" ", sentences).RightToLeft(), font, brush, rect, XStringFormats.TopRight);
 rect.Y += font.Height;
 sentences.Clear();
 }
}
</code></pre>

I'm working with PdfSharp to create some pdf files. Everything works fine except when I try to put some text into the file in a right-to-left language (e.g., Persian) using Drawstring method. Although I choose Unicode encoding in XPdfFontOptions and a suitable font family (e.g., "B Nazanin"), it draws the letters discretely.

<a href="http://i.stack.imgur.com/nOl9B.jpg" rel="nofollow">Here</a> is an image of what I get.

B.T.W, is there any better way to create pdf files?

我正在使用PdfSharp创建一些pdf文件。除了我尝试使用Drawstring方法以从右到左的语言(例如，波斯语)将一些文本放入文件中之外，一切都很正常。虽然我选择了XPdfFontOptions中的Unicode编码和合适的字体系列(例如，"B Nazanin")，但它是离散绘制字母的。是我所得到的一个图像。B.T...
