我正在从页面上的gridview生成PDF(使用iTextSharp)，但是PDF输出有编码问题。例如在页面上:
Aplicação para posicionar
在PDF上显示如下:
Aplicação para posicionar
我是一个直接从gridview生成这个，因为我需要用户输入(例如复选框)，所以我不能从数据库中读取此数据。我假设某种编码/解码是有序的，但我在这里相当茫然。
创建PDF的步骤:
BaseFont helvetica = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, false);
Font helvetica14 = new Font(helvetica, 14, Font.NORMAL);
Font helvetica12BOLDITALIC = new Font(helvetica, 12, Font.BOLDITALIC);
Font helvetica8BOLDITALIC = new Font(helvetica, 8, Font.BOLDITALIC);
Font helvetica6 = new Font(helvetica, 6, Font.NORMAL);
//Create PDF document
Document doc = new Document(PageSize.A4);
MemoryStream outputStream = new MemoryStream();
PdfWriter.GetInstance(doc, outputStream);
doc.Open();
//Add title
doc.Add(new Paragraph(importantlblTitleGlobal + "nnnn", helvetica14));
//Copy the Api Transaction table
if (detailsApiTransactionRowCount > 1)
{
//Create PDF table
PdfPTable tableDetailsInput = new PdfPTable(detailsApiTransactionCellCount);
//Create title table
PdfPCell cell = new PdfPCell(new Phrase("Api Transaction List", helvetica12BOLDITALIC));
cell.BackgroundColor = new BaseColor(128, 128, 128);
cell.Colspan = detailsApiTransactionCellCount;
cell.HorizontalAlignment = 1; //0=Left, 1=Centre, 2=Right
tableDetailsInput.AddCell(cell);
string[] headers = { "Transaction Name", "Transaction Description" };
for (iteratorCell = 0; iteratorCell < detailsApiTransactionCellCount; iteratorCell++)
{
PdfPCell newCell = new PdfPCell(new Phrase(headers[iteratorCell], helvetica8BOLDITALIC));
newCell.BackgroundColor = new BaseColor(192, 192, 192);
tableDetailsInput.AddCell(newCell);
}
//Create content table

提示吗?
编辑:添加新行。页面是UTF-8，当我定义基字体时，我无法在iTextSharp的常量中找到UTF。我刚刚在adobereader中检查了PDF文件的属性，它说它的编码是Ansi。
谢谢。
尝试从网格中解码文本，即改为
apiInputOutputGrid.Rows[iteratorRow].Cells[iteratorCell].Text
HttpUtility.HtmlDecode(apiInputOutputGrid.Rows[iteratorRow].Cells[iteratorCell].Text)
要么是pdf组件的编码问题，pdf的解析，要么是从网格返回的数据可能不是新的信息:)检查网格结果并查看每个字段等。它们都被编码了吗?有些东西是html编码-所以需要弄清楚它是你的网格代码还是pdf代码。
将此添加到您的函数中:
Response.charset="utf-8"
…或者应该是什么字符集，如果不是utf-8，也许是拉丁1?
否则，这篇文章看起来可能与你的有关:Html到pdf的一些字符丢失(itextsharp)
