It is great that you have found other PDF editors you can compare to Perfect PDF 9. The more the merrier. It will be interesting to see what the others produce for the Export to Text as Unicode encoding.
My review is dependent on knowing as much as all the alternatives as possible but I don’t have other PDF editors installed, and the one I use does not export to text using Unicode encoding, so for me, Perfect PDF 9 has been a welcome tool, and to get it free from Sharewareonsale has been the best price.
Since I know you already have Ashampoo PDF Pro v1.11, it seemed like a simple task to see what it produces when it exports to text using Unicode encoding. At least you can knock that one away. Then later, see what the others do and report on them too.
