I encouter a bad render conversion from a RTF file to a PDF file.
I try with the latest Words for Java 13.2.0 but the render is the same.
A string is repeated twice with two differents formats :
You can see in attachment the initial rtf file, the aspose pdf file with double string (the vertical one is bad, the blue one is good ; see in P.png), the pdfcreatof file which is correct.
This is an example, I have a lot of rtf file in this situation.
