Hi All,
While Writing to Excel File using the ClosedXML facing an issue. Above is the error mentioned into caption which I am getting.
Have attached the Excel File which I am trying to Write by passing the DataSet.
Please Reply ASAP.
Thanks,
Samir.
Comments: This also affects us - can reproduce this with the following: ``` byte[] data; using (var stream = new MemoryStream()) { var wb = new XLWorkbook(); wb.AddWorksheet("Sheet1").FirstCell().SetValue("\u0018"); wb.SaveAs(stream); data = stream.ToArray(); } using (var stream = new MemoryStream(data)) { var wb = new XLWorkbook(stream); Assert.AreEqual("\u0018", wb.Worksheets.First().FirstCell().Value); } ``` The above fails on the call to wb.SaveAs, however even if saved correctly the cell value ends up being read as "_x0018_" and the assert will fail. The [ECMA-376 Specification (part 1)](http://www.ecma-international.org/publications/standards/Ecma-376.htm) says the following under the bstr element > Unicode characters that cannot be directly represented in XML as defined by the XML 1.0 specification, shall be escaped using the Unicode numerical character representation escape character format _xHHHH_, where H represents a hexadecimal character in the character's value. [Example: The Unicode character 8 is not permitted in an XML 1.0 document, so it shall be escaped as _x0008_. end example] To store the literal form of an escape sequence, the initial underscore shall itself be escaped (i.e. stored as _x005F_). [Example: The string literal _x0008_ would be stored as _x005F_x0008_. end example] I had a look at how to fix this with the intention of preparing a pull request, but I'm not familiar enough with OpenXml to identify where this encoding method should be applied - at the minimum it needs to be applied to the shared strings, but it looks like this might also apply to other strings too.
