I am trying to create pdf from one html which has chinese char. in this i have got weird prob. the line from html which has chinese char is not completely shown in pdf generated from it.
Below is my html:

<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">

below is my itext renderer code:
StringWriter writer = new StringWriter();
Tidy tidy = new Tidy();
tidy.setTidyMark(false);
tidy.setDocType("omit");
tidy.setXHTML(true);
tidy.setInputEncoding("utf-8");
tidy.setOutputEncoding("utf-8");
//tidy.parse(new StringReader(documentJsoup.toString()), writer);
tidy.parse(new StringReader(inputFileString), writer);
writer.close();
String pdfContent = writer.toString();
// Creating an instance of iText renderer which will be used to generate the pdf from the html document.
ITextRenderer renderer = new ITextRenderer();
/*renderer.setDocument(doc, baseurl);
renderer.layout();
renderer.createPDF(os);
os.flush();
// close all the streams
//fis.close();
//os.close();
//instream.close();
*/
ITextFontResolver resolver = renderer.getFontResolver();
//renderer.getFontResolver().addFont("C:\\Windows\\Fonts\\arialuni.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
resolver.addFont("C:\\Windows\\Fonts\\arialuni.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
renderer.setDocumentFromString(pdfContent);
renderer.layout();
renderer.createPDF(os);

The issue is that Flying-saucer doesn't manage line wrapping in chinese text. It only insert line break on whitespaces. In your case, it means it cannot insert a line break after "nm,,,,", and it doesn't fit on the line.
It is a known bug in flying saucer (see here ), but it's unlikely to be fixed soon.
The only workaround is to insert a whitespace anywhere in your string after the Chinese characters. It will make all the text visible.

Here you need to add font type or font file in your application.
you can find code here itextSharp - html to pdf some turkish characters are missing
this question is also same as your question..
if this helps you then please give points.

I tried adding below css rules into the body class and it worked perfectly.
word-wrap: break-word; word-break: break-all;
"Adding whitespaces" works sometimes (I tried adding spaces after symbols like 。 or 、), but sometimes when there's no symbols it still overflows.
