According to the documentation, the extractText method works poorly for some PDF-files depending on the generator.
Some questions I would think about:
Are the PDFs generated using the same tool?
If not can you access the tool used to generate the greek PDF and use it to generate a test case?
If you are unfortunate the extract method just doesn't work for your PDF and in that case, maybe you have look for another library. I hope it works out for you.
For further actions, you may consider blocking this person and/or reporting abuse
