iText Chunks are written over each other

I have a simple piece of code that splits a sentence (named content in the code) into tokens and then writes tokens in pdf file, but each in new line.
Document document = new Document(PageSize.A4, 20, 20, 20, 20);
PdfWriter.getInstance(document, new FileOutputStream("ticket.pdf"));
document.open();
Font font = FontFactory.getFont(FontFactory.COURIER, 16, BaseColor.BLACK);
String[] tokens = content.split("\\|");
for (String token : tokens) {
Chunk chunk = new Chunk(token, font);
document.add(chunk);
document.add(Chunk.NEWLINE);
}
document.close();
But when I open the result pdf file, all of the tokens (chunks) are written over each other in the first line, like this:
Can anyone point to me what am I doing wrong here? Code is written in Spring Boot with Java 11, and iText version is 5.5.10

PDFBox incorrect text appearance after copy/paste

I’m using PDFBox 2.0.4 to create PDF documents with acroForms. Here is my test code example:
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
PDAcroForm acroForm = new PDAcroForm(document);
document.getDocumentCatalog().setAcroForm(acroForm);
String dir = "../testPdfBox/src/main/resources/fonts/";
PDType0Font font = PDType0Font.load(document, new File(dir + "Roboto-Regular.ttf"));
PDResources resources = new PDResources();
String fontName = resources.add(font).getName();
acroForm.setDefaultResources(resources);
String defaultAppearanceString = format("/%s 12 Tf 0 g", fontName);
acroForm.setDefaultAppearance(defaultAppearanceString);
PDTextField field = new PDTextField(acroForm);
field.setPartialName("SampleField");
field.setDefaultAppearance(defaultAppearanceString);
acroForm.getFields().add(field);
PDAnnotationWidget widget = field.getWidgets().get(0);
PDRectangle rect = new PDRectangle(50, 750, 200, 50);
widget.setRectangle(rect);
widget.setPage(page);
widget.setPrinted(true);
page.getAnnotations().add(widget);
field.setValue("Sample field 123456");
acroForm.flatten();
document.save("target/SimpleForm.pdf");
document.close();
Everything works fine. But when I try to copy text from the created document and paste it to the NotePad or Word it becomes squares.

I search a lot about this problem. The most popular answer is that there is no toUnicode cmap in created PDF. So I explore my document with CanOpener for Acrobat:
Yes, there is no toUnicode cmap, but everything works properly, if not to use acroForm.flatten(). When form fields are not flattened, I can copy/paste text from the document and it looks correct. Nevertheless I need all fields to be flattened.
So, I have two questions:
Why there is a problem with copy/pasting text in flattened form, and everything is ok in non-flattened?
What can I do to avoid problem with text copy/pasting?
Is there only one solution - to create toUnicode CMap by my own, like in this example?
My test pdf files are available here.

Please replace
PDType0Font font = PDType0Font.load(document, new File(dir + "Roboto-Regular.ttf"));
with
PDType0Font font = PDType0Font.load(document, new FileInputStream(dir + "Roboto-Regular.ttf"), false);
This makes sure that the font is embedded in full and not just as a subset.

Changing Font on PDF Rotated Text

I'm using iText to create barcodes on a PDF with the same format as this one:
The problem is the the left number, the first zero digits must be smaller, while the rest of the numbers must also be bold. "T.T.C." also has to be even smaller (it doesn't have to be on another line).
I was able to rotate the number with the following code:
String price = "23000 T.T.C.";
PdfContentByte cb = docWriter.getDirectContent();
PdfTemplate textTemplate = cb.createTemplate(50, 50);
ColumnText columnText = new ColumnText(textTemplate);
columnText.setSimpleColumn(0, 0, 50, 50);
columnText.addElement(new Paragraph(price));
columnText.go();
Image image;
image = Image.getInstance(textTemplate);
image.setAlignment(Image.MIDDLE);
image.setRotationDegrees(90);
doc.add(image);
The problem is that I cannot find a way online to change the font of certain characters of the String price when it is printed on the PDF.

I have created a small Proof of Concept that results in a PDF that looks like this:
As you can see, it has text in different sizes and styles. It also has a bar code that is rotated.
Take a look at the RotatedText example:
public void createPdf(String dest) throws IOException, DocumentException {
// step 1
Document document = new Document(new Rectangle(60, 120), 5, 5, 5, 5);
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(dest));
// step 3
document.open();
// step 4
PdfContentByte canvas = writer.getDirectContent();
Font big_bold = new Font(FontFamily.HELVETICA, 12, Font.BOLD);
Font small_bold = new Font(FontFamily.HELVETICA, 6, Font.BOLD);
Font regular = new Font(FontFamily.HELVETICA, 6);
Paragraph p1 = new Paragraph();
p1.add(new Chunk("23", big_bold));
p1.add(new Chunk("000", small_bold));
document.add(p1);
Paragraph p2 = new Paragraph("T.T.C.", regular);
p2.setAlignment(Element.ALIGN_RIGHT);
document.add(p2);
BarcodeEAN barcode = new BarcodeEAN();
barcode.setCodeType(Barcode.EAN8);
barcode.setCode("12345678");
Rectangle rect = barcode.getBarcodeSize();
PdfTemplate template = canvas.createTemplate(rect.getWidth(), rect.getHeight() + 10);
ColumnText.showTextAligned(template, Element.ALIGN_LEFT,
new Phrase("DARK GRAY", regular), 0, rect.getHeight() + 2, 0);
barcode.placeBarcode(template, BaseColor.BLACK, BaseColor.BLACK);
Image image = Image.getInstance(template);
image.setRotationDegrees(90);
document.add(image);
Paragraph p3 = new Paragraph("SMALL", regular);
p3.setAlignment(Element.ALIGN_CENTER);
document.add(p3);
// step 5
document.close();
}
This example solves all of your issues:
You want a Paragraph to use different fonts: compose a Paragraph using different Chunk objects.
You want to add extra text on top of a bar code: add the bar code to a PdfTemplate and add the extra text using ColumnText.showTextAligned() (not that you can also compose a Phrase using different Chunk objects if you need more than one font in that extra text).
You want to rotate the bar code: wrap the PdfTemplate inside an Image object and rotate the image.
You can check the result: rotated_text.pdf
I hope this helps.

Icepdf special character rendering issue

I use itext library for creating PDF file because has very detailed rendering functions for PDF creation. When user click the button i write a template and fill the blank cells from DB everytime.
Than i use Icepdf library for show to user and taking output of the created pdf file.
But Icepdf has some character encoding problem i think. When PDf created and callled by Icepdf one of Turkish character looks as square. Turkish characters can be seen at this link. All characters rendered succesfully but eighth character at the picture is not.
When i go to filepath of created pdf file (created by itext library) and open it manually with Adobe Acrobat Reader all characters showing correctly. But if programaticly Icepdf open the file and show to user, eighth character at the picture looks as square.
I need change character encoding of Icepdf but i can't yet. Reading many articles about character and Font encoding of Icepdf but i have not yet succeeded. If i solve this character problem my application ready to deploy.
The generated PDF file can be downloaded here.
When I open this file with Adobe Acrobat it looks like this:
When I open the file with IcePDF programaticly it looks like thi:
Also i read some questions and answers about this on Stackoverflow but none of them have an accepted answer/help.
Code used to create the file path:
File fUrl = new File(CreateAndViewPdf
.class
.getProtectionDomain()
.getCodeSource()
.getLocation()
.getPath()
);
String path = fUrl
.toString()
.substring(0,fUrl.toString().lastIndexOf(File.separator))
.replace("%20", " ") + "\\hello.pdf";
Code for the createPdf() method:
public void createPdf()throws DocumentException, IOException {
BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA, "ISO-8859-9", BaseFont.EMBEDDED);
Document document = new Document(PageSize.A5);
PdfWriter.getInstance(document, new FileOutputStream(path));
document.setMargins(10, 10, 10, 10);
document.setMarginMirroring(true);
document.open();
Font font = new Font( bf );
PdfPCell cell;
PdfPTable table = new PdfPTable(2);
font = new Font( bf );
font.setSize(15);
font.setStyle("bold");
cell = new PdfPCell(new Phrase("Sender\n"+"Information", font));
cell.setPaddingBottom(7);
cell.setHorizontalAlignment(Element.ALIGN_CENTER);
cell.setVerticalAlignment(Element.ALIGN_MIDDLE);
table.addCell(cell);
font = new Font( bf );
font.setSize(12);
font.setStyle("normal");
cell = new PdfPCell(new Phrase("â ç ğ ı İ î ö ş ü û\n\n"+"Â Ç Ğ I İ Î Ö Ş Ü Û",font));
cell.setPaddingBottom(7);
cell.setVerticalAlignment(Element.ALIGN_MIDDLE);

table.setWidths(new int[]{50,200});
table.setWidthPercentage(100);
table.setSpacingAfter(10);
table.setSpacingBefore(10);
document.add(table);
document.close();
}
Code for the viewPdf() method:
public void viewPdf(String fileP)throws IOException, InterruptedException {
String filePath = fileP;
SwingController controller = new SwingController();
SwingViewBuilder factory = new SwingViewBuilder(controller);
JPanel viewerComponentPanel = factory.buildViewerPanel();
controller.getDocumentViewController().setAnnotationCallback(
new org.icepdf.ri.common.MyAnnotationCallback(
controller.getDocumentViewController()));
Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
CreateAndViewPdf.this.getContentPane().add(viewerComponentPanel);
CreateAndViewPdf.this.setSize(new Dimension(screen.width/2,screen.height));
CreateAndViewPdf.this.setLocationRelativeTo(null);
controller.openDocument(filePath);
}

--- SOLVED ---
Firstly, thanks for the router comment to #Mike 'Pomax' Kamermans
After reading him/her comments begin investigating " how can i embed the spesific font file to PDF with iText " After 1-2 days later, i found solution just like below;
Going to Windows Control Panel\Appearance and Personalization\Fonts and copy the times.ttf (which tested all special characters supported font) file to my Java Application resources container.
Than i add below lines to top of my createPDF method.
Font fontBase = FontFactory.getFont("/resources/times.ttf",
BaseFont.IDENTITY_H,
BaseFont.EMBEDDED,
0.8f, Font.NORMAL,
BaseColor.BLACK);
BaseFont bf = fontBase.getBaseFont();
After this, viewPdf() method get the document to screen with all special characters truely rendering.

PdfPcell empty output of Arabic strings

I have that part of code:
//Staff
// Title font
BaseFont titleBf = null;
try {
titleBf = BaseFont.createFont(BaseFont.TIMES_ROMAN,BaseFont.CP1252, BaseFont.EMBEDDED);
} catch (IOException e) {
System.out.println(e.getMessage());
}
com.itextpdf.text.Font titleFont = new com.itextpdf.text.Font(titleBf,24);
titleFont.setColor(new BaseColor(0, 0, 204));
/*
* Pdf creation
*/
Document document = new Document();
PdfWriter.getInstance(document,new FileOutputStream(fc.getSelectedFile() + ".pdf"));
document.open();
/*
* Title
*/
Paragraph p = new Paragraph("مرحبا بكم",titleFont);
p.setSpacingAfter(20);
p.setAlignment(1); // Center
document.add(p);
//Staff
document.close();
The output was empty.
Even when I tried to add simple pdfpcell, I got same result, here is the way:
com.itextpdf.text.Font fontNormal = FontFactory.getFont(
("arialuni.ttf"), BaseFont.CP1252, BaseFont.EMBEDDED,
8, com.itextpdf.text.Font.NORMAL);
Chunk chunkArabic = new Chunk("مرحبا العالم", fontNormal);
infoTab.addCell(new PdfPCell(new Phrase(chunkArabic)));
document.add(infoTab);

Different problems may be at play.
Encoding: You are putting Arabic text in your source code. If you save your Java file using the wrong encoding, that text will become corrupt. If you compile your Java file using the wrong encoding, that text will become corrupt. And so on. I hope you get the idea. Store literal text like this: "\u0644\u0648\u0631\u0627\u0646\u0633 \u0627\u0644\u0639\u0631\u0628" to avoid problems like this.
As documented in Chapter 11 of my book, right-to-left writing and Arabic ligatures are only supported in the context of PdfPCell and ColumnText. I see that you're using PdfPCell, but I don't see you using cell.setRunDirection(PdfWriter.RUN_DIRECTION_RTL); anywhere. That's wrong.
You are using an object fontNormal, but you're not telling us which font you're actually using. For instance: if you're using the standard Type1 font Helvetica, no text will show up, because Helvetica doesn't know how to render Arabic text.
Amendment: You've now updated your question, showing that you're using "arialuni.ttf". However, you are using the wrong encoding: CP1252 is the encoding for the Latin Alphabet. You should use BaseFont.IDENTITY_H.
Update: looking at the update of your question as well as the extra comment, I see two major errors.
You are assuming that the name of the font is "arialuni.ttf". That's the font file, but not the font name. Also: you are asking the FontFactory for this font, but did you tell the FontFactory where to look for fonts? Are you sure the FontFactory can locate c:/windows/fonts/ or whatever directory the file arialuni.ttf is stored.
You are declaring a font, but you're not using it: Paragraph p = new Paragraph("\u062D\u064A\u0633\u0648"); creates a Paragraph using the default font.
This is code that works:
BaseFont bf = BaseFont.createFont(
"c://windows/fonts/arialuni.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font font = new Font(bf, 8);
PdfPTable table = new PdfPTable(1);
PdfPCell cell = new PdfPCell(new Phrase("\u062D\u064A\u0633\u0648", font));
cell.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);
table.addCell(cell);
document.add(table);
The result looks like this (zoomed in):
