I have a very simple docx document with the same two words in Thai written on two different lines. The words and the paragraphs are styled the same. Thai font is Tahoma and is embedded into the docx document.
When I transform the document to PDF using transformDocument, the word on the first line is correct while the word on the second line is not displayed. Its characters are being replaced with squares.
It can't be a font problem since:
- the font is embedded
- the first word, exactly the same as the second word, is displayed correctly
