Hi,
Yes, this doesn't work properly. There is an ongoing effort about this
for 3.0 but it is incomplete, it supports only Bengali. See the
GsubWorkerForBengali and the GsubWorkerFactory classes, maybe you can
use this as inspiration to write something for Devanagari.

Hello,
I am writing to request assistance with modifying the encoding rules
for Devanagari script in the PDFBox library. Our team is working on a
research-based project that involves coding a rendering engine/library
for Nepali Devanagari script in PDF documents using Scala programming
language and the PDFBox library.
We have encountered issues with the current encoding rules for
Devanagari script in the library. that we are trying to solve The
script is not rendering properly in the PDF documents generated by our
program, and we suspect that this issue may be due to the encoding rules.
For Instance when we run this program
public class App {
public static void main(String args[])throws Exception {
PDDocument document =new PDDocument();
PDPage page =new PDPage();
document.addPage(page);
PDPageContentStream contentStream =new PDPageContentStream(document,
page);
PDFont unicodeFont =PDType0Font.load(document,new
File("arial-unicode-ms.ttf"));
contentStream.setFont(unicodeFont,14);
contentStream.beginText();
contentStream.moveTextPositionByAmount(100,200);
contentStream.drawString("नेपालीहरू फिनल्याण्डमा राष्ट्रिय");
contentStream.endText();
contentStream.beginText();
contentStream.moveTextPositionByAmount(100,300);
contentStream.endText();
contentStream.close();
document.save("test.pdf");
document.close();
}
The resulting output is as follows
image.png
PDF box doesn't replace for half consonants and displays the order of
the left dependent vowel incorrectly(for this particular example;
there are much more issues)
We would greatly appreciate any guidance on where in the PDFBox
library code we can modify the encoding rules for the Devanagari
script since it would save us a lot of time and effort.
Thank you very much for your help and support. We look forward to
hearing back from you soon.
