[jira] [Commented] (PDFBOX-4100) PDFBox not displaying Tamil
Characters properly using Arial Unicode Font
[ https://issues.apache.org/jira/browse/PDFBOX-4100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16354567#comment-16354567 ]
Tilman Hausherr commented on PDFBOX-4100:
-----------------------------------------
This isn't supported... the first glyph, "ரொ" is [\u0BB0\u0BCA|https://chars.suikawiki.org/string?s=%5Cu0BB0%5Cu0BCA] . PDFBox (or java) takes each 16 bit value separately. You'd need to find a way to pass every single glyph, as in the PDF attached. I don't know if this is possible, PDFBox does not support "complex scripts". It is unclear if Tamil is this.

> I am loading Arial Unicode Font and trying to render some Tamil Language text. It is not rendering in proper order
> PDDocument document = new PDDocument();
> font = PDType0Font .load(document, getClass().getClassLoader().getResourceAsStream("fonts/Arial-Unicode-Regular.ttf"));
> page = new PDPage(PDRectangle.A4);
> document.addPage(page);
> PDPageContentStream stream = new PDPageContentStream(document, page);
