I use the free version of PDFill for editing PDF's. The full editor costs $20.
This includes a form tool and says it can handle International languages. The Editor is included as a free Trial if you want to experiment to see if it works for you.
The home page has links to reviews.
Also note that older versions of Acrobat Pro do work in Win7. Acrobat 9+ is fully compatible per MS. ver8 throws an error but just needs a driver manually extracted. Even version 7 will install - just turn off PDFMaker during the install and use a free PDF printer for printing. It throws an error but works fine. Evidently even 6 and 5.1 can be used with Compatibility tweaking. I installed 6 to install a 7 upgrade as it didn't know how to find the prior media.
