I just got the latest from Codeplex. I am getting 230+ errors in the XGraphicsPdfRenderer.cs file - Unexpected character errors, as well as a number of syntax errors caused by the Unexpected characters.
I did find and attempt the fix mentioned for the Unicode encoding, no effect. Note that this was a simple opening of the BuildAll-PdfSharp solution followed by Solution Clean, Solution Re-build All. No files had been opened in the editor at that time.
