Team,
I am not getting PDFBox to render malayalam (one of the Indic script) text
properly. If Ligature substitution works then this should work. I am using
3.0.0-RC1 version.
String text = "വകുപ്പ് 1 മനുഷ്യരെല്ലാവരും തുല്യാവകാശങ്ങളോടും";
PDDocument doc = *new* PDDocument();
PDFont font = PDType0Font.load(doc, new
File("/Users/kishore/Downloads/ML-NILA01_NewLipi.ttf"));
PDPage page = *new* PDPage();
doc.addPage(page);
PDPageContentStream contentStream = *new* PDPageContentStream(doc, page);
contentStream.beginText();
contentStream.newLineAtOffset(25, 700);
contentStream.setFont(font,12 );
contentStream.showText(text);
contentStream.endText();
contentStream.close();
Do we have the support for GSUB tables now? Am I doing anything wrong here?
Please suggest.
The output I get is -
!pdf-output.png!
versus the input text text
വകുപ്പ് 1 മനുഷ്യരെല്ലാവരും തുല്യാവകാശങ്ങളോടും
Here GSUB substitution is not happening.

> Implemented proper rendering of Indian languages, which need extensive Glyph
> substitution. The GSUB table has been read and used effectively to replace
> some compound words with their respective Glyphs. All tests are passing. I
> have tested this for the Bengali font. Please review these changes and let me
> know if it makes sense to incorporate these.
