How to embed an standard font into generated PDF with PDFBox

I need to add some text to PDF/A files using the Apache PDFBox library for Java. The problem is that, because it needs to be a valid PDF/A file, all the used fonts must be embedded in it. I know that I can embed a TTF font using PDFBox, but I'd like to avoid having to provide a font file with the application, so I was wondering if there's a way to embed one of the standard fonts available in PDFBox as if it was external.
For example, when I write something using one of the standard fonts, the PDF validator complains about this:
I've used the following code to write the text:
PDFont standardFont = PDType1Font.HELVETICA_BOLD;
PDPage pag = new PDPage();
pag.setResources(new PDResources());
PDPageContentStream contentStream = new PDPageContentStream(pdfFile, pag);
//Begin the Content stream
contentStream.beginText();
//Setting the font to the Content stream
contentStream.setFont(standardFont, 12);
//Setting the position for the line
contentStream.newLineAtOffset(25, 500);
//Adding text in the form of string
contentStream.showText("JUST A SAMPLE STRING");
//Ending the content stream
contentStream.endText();
//Closing the content stream
contentStream.close();
pdfFile.addPage(pag);
pdfFile.save(file);
pdfFile.close();
Is there any option to force the embed of the font when setting it?
Thanks in advance,

There is only one font embedded in PDFBox. You can use it this way:
PDFont font = PDType0Font.load(doc, SomePdfboxClass.class.getResourceAsStream(
"/org/apache/pdfbox/resources/ttf/LiberationSans-Regular.ttf"));

How to display Chinese characters in java web applications?

I use Itext 5 to create pdf file. I refer to https://developers.itextpdf.com/examples/itext-action-second-edition/chapter-1 and get a pdf. When I open it, Chinese characters display normally.
But I develop web applications like https://developers.itextpdf.com/examples/itext-action-second-edition/chapter-9 described. Chinese characters is blank when pdf show in browser.
My font code is
String chFontPath = "c:\fonts\xxx.ttf";
BaseFont chBaseFont = BaseFont.CreateFont(chFontPath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font font = new Font(chBaseFont, 12);
Does anybody know?

If you embed the font using an absolute path, probably the path will be broken for any webapp you develop. Use a relative path instead for any embeddable (fonts, images, etc) so you can place them in server without any trouble.
I think Bruno's answer about a relative anchor could help you to set up a relative path for your font: https://stackoverflow.com/a/27064142/4048864

showing emoji in pdf or excel

I have the data containing emoji in database. I want to display in the generated document such as pdf or in excel format.
I am using spring boot application. Please suggest any java library for generating either PDF or excel which supports emoji.

iText supports this. Assuming
your emoji is a unicode character
you use a font that contains the correct glyph for this unicode character
Best way to test this is to try it.
This is how to get started with iText:
https://developers.itextpdf.com/content/itext-7-jump-start-tutorial/installing-itext-7
And this is a small code-snippet that adds text to a document with different fonts:
PdfDocument pdf = new PdfDocument(new PdfWriter(dest));
Document document = new Document(pdf);
PdfFont font = PdfFontFactory.createFont(FontConstants.TIMES_ROMAN);
PdfFont bold = PdfFontFactory.createFont(FontConstants.TIMES_BOLD);
Text title =
new Text("The Strange Case of Dr. Jekyll and Mr. Hyde").setFont(bold);
Text author = new Text("Robert Louis Stevenson").setFont(font);
Paragraph p = new Paragraph().add(title).add(" by ").add(author);
document.add(p);
document.close();

docx conversion to pdf in korean font

Hope someone can help me. It's about docx to pdf conversion having korean sign in docx document.
I'm able to convert a docx document to pdf with docx4j.
In pdf document, I can see the result. But if my docx document contains korean font, I can't see any korean font in my pdf document except the latin numbers.
What do I have to do to get korean font in my pdf from the docx document?
Here is my code:
File docXFile ="E:/contract2Files/test.docx";
WordprocessingMLPackage wordprocessingMLPackage = WordprocessingMLPackage.load(docXFile);
String out = docXFile .replace("docx","pdf");
File pdfFile = new File(out);
OutputStream pdfFileOs = new java.io.FileOutputStream(pdfFile);
org.docx4j.convert.out.pdf.PdfConversion c = new JanoPdfConversion(wordprocessingMLPackage);
c.output(pdfFileOs);

Please try http://www.docx4java.org/docx4j/docx4j-3_0-beta2.zip (link updated 15 Nov)
You might need to configure your font mapper, though things work out of the box with the Identity mapper on my Windows box, since I have the relevant font installed.
If this doesn't help, please put a sample docx somewhere StackOverflow users can see it.

thanks again. I tried the newest jar file with this code passage and it worked!!! Now I get the korean letters into pdf. Thank again.
ThemePart themePart =
wordprocessingMLPackage.getMainDocumentPart().getThemePart();
org.docx4j.dml.BaseStyles.FontScheme fontScheme = themePart.getFontScheme();
org.docx4j.dml.TextFont textFont = fontScheme.getMinorFont().getLatin();
textFont.setTypeface("Malgun Gothic");
