iText pdf not displaying Chinese characters when using NOTO fonts or Source Hans

I am trying to use NOTO fonts (https://www.google.com/get/noto/) to display Chinese characters. Here is my sample code,a modified sample code from iText.
public void createPdf(String filename) throws IOException, DocumentException {
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream(filename));
document.open();
//This is simple English Font
FontFactory.register("c:/temp/fonts/NotoSerif-Bold.ttf", "my_nato_font");
Font myBoldFont = FontFactory.getFont("my_nato_font");
BaseFont bf = myBoldFont.getBaseFont();
document.add(new Paragraph(bf.getPostscriptFontName(), myBoldFont));
//This is Chinese font
//Option 1 :
Font myAdobeTypekit = FontFactory.getFont("SourceHanSansSC-Regular", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
//Option 2 :
/*FontFactory.register("C:/temp/AdobeFonts/source-han-sans-1.001R/OTF/SimplifiedChinese/SourceHanSansSC-Regular.otf", "my_hans_font");
Font myAdobeTypekit = FontFactory.getFont("my_hans_font", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);*/
document.add(Chunk.NEWLINE);
document.add(new Paragraph("高興", myAdobeTypekit));
document.add(Chunk.NEWLINE);
//simplified chinese
document.add(new Paragraph("朝辞白帝彩云间", myAdobeTypekit));
document.add(Chunk.NEWLINE);
document.add(new Paragraph("高兴", myAdobeTypekit));
document.add(new Paragraph("The Source Han Sans Traditional Chinese ", myAdobeTypekit));
document.close();
}
I have downloaded the fonts files on my machine. I am using two approaches
To use the equivalent font family in Adobe
Embed the otf file in pdf
Using approach 1, I would expect the Chinese characters to be displayed in pdf but English text is displayed and it is blank for Chinese characters.
Using approach 2, when I try embedding the fonts with pdf, which is not the path I would like to take, there is error in opening pdf.
Update :
If I look at this example http://itextpdf.com/examples/iia.php?id=214
and in this code
public void createPdf(String filename, boolean appearances, boolean font)
throws IOException, DocumentException {
// step 1
Document document = new Document();
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(filename));
// step 3
document.open();
// step 4
writer.getAcroForm().setNeedAppearances(appearances);
TextField text = new TextField(writer, new Rectangle(36, 806, 559, 780), "description");
text.setOptions(TextField.MULTILINE);
if (font) {
BaseFont unicode =
BaseFont.createFont("c:/windows/fonts/arialuni.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
text.setExtensionFont(BaseFont.createFont());
ArrayList<BaseFont> list = new ArrayList<BaseFont>();
list.add(unicode);
text.setSubstitutionFonts(list);
BaseFont f= (BaseFont)text.getSubstitutionFonts().get(0);
System.out.println(f.getPostscriptFontName());
}
text.setText(TEXT);
writer.addAnnotation(text.getTextField());
// step 5
document.close();
}
I substitute, c:/windows/fonts/arialuni.ttf with C:/temp/fonts/NotoSansCJKtc-Thin.otf , I do not see the Chinese characters. The text to convert now is
public static final String TEXT = "These are the protagonists in 'Hero', a movie by Zhang Yimou:\n"
+ "\u7121\u540d (Nameless), \u6b98\u528d (Broken Sword), "
+ "\u98db\u96ea (Flying Snow), \u5982\u6708 (Moon), "
+ "\u79e6\u738b (the King), and \u9577\u7a7a (Sky).";

Clearly you are using the wrong font. I have downloaded the fonts from the link you posted. You are using NotoSerif-Bold.ttf, a font that does not support Chinese. However, the ZIP file also contains fonts with CJK in the font name. As described on the site you refer to, CJK stands for Chinese, Japanese and Korean. Use one of those CJK fonts and you'll be able to product Chinese text in your PDF.
Take a look at the NotoExample in which I use one of the fonts from the ZIP file you refer to. It creates a PDF that looks like this:
This is the code I used:
public static final String FONT = "resources/fonts/NotoSansCJKsc-Regular.otf";
public static final String TEXT = "These are the protagonists in 'Hero', a movie by Zhang Yimou:\n"
+ "\u7121\u540d (Nameless), \u6b98\u528d (Broken Sword), "
+ "\u98db\u96ea (Flying Snow), \u5982\u6708 (Moon), "
+ "\u79e6\u738b (the King), and \u9577\u7a7a (Sky).";
public static final String CHINESE = "\u5341\u950a\u57cb\u4f0f";
public static final String JAPANESE = "\u8ab0\u3082\u77e5\u3089\u306a\u3044";
public static final String KOREAN = "\ube48\uc9d1";
public void createPdf(String dest) throws IOException, DocumentException {
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream(DEST));
document.open();
Font font = FontFactory.getFont(FONT, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Paragraph p = new Paragraph(TEXT, font);
document.add(p);
document.add(new Paragraph(CHINESE, font));
document.add(new Paragraph(JAPANESE, font));
document.add(new Paragraph(KOREAN, font));
document.close();
}
You claim that Adobe Reader XI doesn't show the Chinese glyphs, but instead shows a "Cannot extract the embedded Font" message. I can not reproduce this [*]. I have even used Preflight in Adobe Acrobat as indicated here, but no errors were found:
[*] Update: this problem can be reproduced if you use iText 4.2.x, a version that was released by somebody unknown to iText Group NV. Please use iText versions higher than 5 only.

Java iText using Lithuanian letters

I am trying to create PDF file with java and I need to use Lithuanian letters within file. I tried to use html code and use htmlWorker to parse it, however it does not work on most letters(it works on some). If anyone could help me with this I would gladly appreciate it.
try {
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream(pathy));
document.open();
HTMLWorker htmlWorker = new HTMLWorker(document);
String s = ("<html>ĄąĘęŪūČŠ"
+ "ŽčšžĖėĮįŲų</html>");
htmlWorker.parse(new StringReader(s));
document.close();
}
catch(Exception e2){
}
I solved my issue by using unicode, not sure why it doesn't work with html code still...
Document document = new Document();
try {
PdfWriter.getInstance(document, new FileOutputStream(pathy));
document.open();
BaseFont bfComic = BaseFont.createFont("c:\\windows\\fonts\\arial.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
document.add(new Paragraph("ąĄčČęĘėĖįĮšŠųŲūŪžŽ", new Font(bfComic, 12)));
} catch (Exception e2) {
System.err.println(e2.getMessage());
}
document.close();

Finding trouble to change installed font using iText library

So I was trying to use this font I installed called "Tengwar Quenya-1 Regular" and it didn't work, it keep writing de PDF document with the default font. So I tried to use the downloaded file, by using EMBED method, and it is still printing the default font, I wondering if anyone had tried this before, and could tell me what I am doing wrong. Check the code:
public void testePdf(){
Document document = new Document();
String filename = "C:\\Users\\Marcelo\\Downloads\\tengwar_quenya\\QUENCAP1.TFF";
FontFactory.register(filename);
Font fonte = FontFactory.getFont(filename, BaseFont.CP1252, BaseFont.EMBEDDED);
try {
PdfWriter.getInstance(document,
new FileOutputStream(filename+ "HelloWorld.pdf"));
document.open();
document.add(new Paragraph("A Hello World PDF document.", fonte));
document.close(); // no need to close PDFwriter?
} catch (DocumentException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
It compiles fine, just not with the font I selected. If it is a glyph instead of a caracter, will it be a problem?

I have Googled for the font you mention. I have downloaded it and I have made a small SSCCE that you can download here: TengwarQuenya1
This is the code:
public static final String FONT = "resources/fonts/QUENCAP1.TTF";
public void createPdf(String dest) throws IOException, DocumentException {
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream(DEST));
document.open();
Font f1 = FontFactory.getFont(FONT, BaseFont.WINANSI, BaseFont.EMBEDDED, 12);
document.add(new Paragraph("A Hello World PDF document.", f1));
document.close();
}
This is the result: tengwarquenya1.pdf
I'm not sure what the resulting text means, but it doesn't look like the default font to me.
In other words: I can't reproduce the problem. Note that you don't need to register a font if you pass its file path to the FontFactory. Obviously, my font path is different from yours. I think that yours is wrong. Try putting the ".TTF" file in another location.

pdfwriter doesn't translate special characters

I have HTML file with an external CSS. I want to create PDF from the HTML file, but the endcoing doesn't work. HTML file works fine, but after transfering to PDF, some characters in PDF are missing. (čřě...) It happens even if I set the Charset in PDFWriter constructor.
How do I solve this, please?
public void createPDF() {
try {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(username + ID + ".pdf"));
document.open();
String hovinko = username + ID + ".html";
XMLWorkerHelper.getInstance().parseXHtml(writer, document, new FileInputStream(hovinko), Charset.forName("UTF-8"));
document.close();
System.out.println("PDF Created!");
} catch (Exception ex) {
ex.printStackTrace();
}
}

Did you try to convert your special characters before writing them to your PDF?
yourHTMLString.replaceAll(oldChar, newChar);
ć = ć
ř = ř
ě = ě
If you need more special characters, visit this link.
EDIT: Then try this out, it worked for me:
BaseFont basefont = BaseFont.createFont("C:/Windows/Fonts/ARIAL.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font font = new Font(basefont, 12);
document.add(new Paragraph("čřě", font));

Try it with below logic. It worked for me:
InputStream is = new ByteArrayInputStream(hovinko.getBytes(Charset.forName("UTF-8")));
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is, Charset.forName("UTF-8"));
I used xmlworker version 5.5.12 and itextpdf version 5.5.12.

I was strugling with sam problem (Polish special signs).
For me solution was to write a good font-family in html code.
