pdfCalligraph gives advanced typography support when creating PDF documents.
Off the-shelf PDF creators often have problems with character interactions or writing systems such as the Indic Devanagari family, Arabic, Hebrew and more. They also struggle with compound characters that are difficult to separate in text, making text extraction difficult. pdfCalligraph solves this challenge by offering a neat conversion to PDF for these scripts and stylistic improvements, so that you can use the font features and writing systems of your choice in PDF.
