I am trying to convert hindi html into pdf using code

pd4ml.useTTF("java:font", true);
pd4ml.setDefaultTTFs("Mangal", "Times New Roman", "Arial");
pd4ml.render(url, fos);

But my input is : क्रम संख्या
and output is : करम सखया

Please help

PD4ML does not support a ligaturizing of Hindi fonts.

If you point us to a good algorithm, which describes it, we'll implement it on our code.

Hi,

I am also facing issues related to rendering hindi text in PDF .
PFB the code snippet : htmlString is some hindi text
It generates some other fonts or ?? in the PDF.
ByteArrayOutputStream out = new ByteArrayOutputStream(10240);
StringReader isr = new StringReader(htmlString);
pd4ml.render(isr, out, new URL(urlBase), IEncoding.STRING_ENCODING);


Could you please let me know the configuration needed for the same.

Hi,

Could you please share more configuration details. With my code it is not able to comprehend hindi font at all.

The issue is known. PD4ML does not implement a ligaturizing for Indic languages as we have found neither good tech description of the algorithm nor a reference implementation.

If you can point us to good info sources - we'll be happy to implement and to include it to PD4ML.

By default PD4ML converts to PDF characters, belong to Latin-1 charset only using built-in Adobe fonts (Helvetica, Times New Roman and Courier New). In order to output national or special characters you would need to configure and utilize TTF embedding feature of PD4ML Pro. See:

Thanks for the sharing.

Is there any update on this. Does the latest versions support Mangal Font.

There is no problem with Mangal font itself. The issue is caused by Hindi ligaturizing. In the most recent v4.0.9fx2 snapshot build we added the basic ligaturizer and currently are in process of refining it. After it is finished, we'll copy the code also to PD4ML v3 branch.
