Hi Tilman, I’m not sure about the origin of my PDF, as it was uploaded by our client, so I can’t confirm whether it was generated by PDFBox.
I’m not certain about the font causing the garbled text; I suspect it may not be SimSun, but another font. It seems that your computer may be missing this font, which is causing the issue. To help, I’ve copied all my fonts from C:\Windows\Fonts and uploaded them to Google Drive in a folder named "font," with a total of 370 fonts. Feel free to download them and give it a try if needed. I’ve just created a JIRA account using the email x279968...@gmail.com, and my username is vincent lee, which is a temporary English name I gave myself. My previous emails showed my Chinese name. Once you approve my request, I will follow your instructions to submit a bug report.
