Text is not Rendered while add Arabic Text in PDF using Noto Sans Arabic Font in Java

Aspose pdf 21.10 for java does not handle all Arabic chars e.g:

var font = FontRepository.findFont("Noto Sans Arabic");

var textState = new TextState();
textState.setFontSize(9);
textState.setFontStyle(FontStyles.Regular);
textState.setForegroundColor(Color.getBlack());
textState.setLineSpacing(5F);
textState.setFont(font);

var text = "ق - ن - ف";

System.out.println(font.doesFontContainAllCharacters(text));

var textFragment = new TextFragment(text);
textFragment.getTextState().applyChangesFrom(textState);

var document = new Document();
var page = document.getPages().add();
page.getParagraphs().add(textFragment);
document.save("HelloWorld_out.pdf");

Output HelloWorld_out.pdf instead of “ق - ن - ف” contains " - - ", but some other Arabic chars works fine - please check above example with “أسعار”.

This occurs with Noto Sans Arabic Noto Sans Arabic - Google Fonts which handle all Arabic chars (including “ق - ن - ف”)

Moreover font.doesFontContainAllCharacters(text) returns true

Thanks!

Hopefully, the fix of this issue will be available in the next version of Aspose.PDF for Java i.e. 22.8. We will inform you via this forum thread once there is an update available on it.

The issues you have found earlier (filed as PDFJAVA-41946) have been fixed in Aspose.PDF for Java 22.9.

@tahir.manzoor
The issue still exists. We checked it on this example.

Font font= FontRepository.findFont("Noto Sans Regular");
TextState tstate= new TextState();
tstate.setFont(font);

Document document = new Document();

document.getPageInfo().setDefaultTextState(tstate);

Page page = document.getPages().add();
TextFragment paragraph = new TextFragment("مرة أخرى إلى الأقلام أو المضخات اللاصقة الآن.");
paragraph.getTextState().applyChangesFrom(tstate);
page.getParagraphs().add(paragraph);

document.save("Example.pdf");

Result in pdf file:

After copying text from a pdf file and pasting it into a word document, the text looks correct. Looks like pdf cut the text. Can you investigate the issue again?

Hi! Do you have any updates on when we can expect it to be resolved?
Thanks!

@wjeczalik

We have worked over issue and noticed that this issue is more related to fonts. Could you please provide the exact font file that cause the test cut problem. It could be the situation when glyphs in the font are designed in a way that symbols are placed out of the visible line of text. So, we need the exact font file to reproduce and fix the issue. Thanks for your cooperation.

@tahir.manzoor
Sure thing! Here’s a link to the font Noto Sans Arabic - Google Fonts
Please let us know if you need anything else or you have any updates.
