PDFsharp & MigraDoc Foundation

I downloaded PDFSharp-1.2.1269.beta+MigraDocLite-1.2.2546

Unzip with winrar 3.47

I found PDFsharp\code\PdfSharp\PdfSharp.Pdf.IO\Chars.cs

line 76,77 like this:
public const char SoftHyphen = '?; // char(173)
public const char Currency = '?;

And other char error.

MY OS:Winsows XP SP2 chinese

I downloaded again and it is also.

I didn't know why.
