Topic: /FlateDecode filter and strange things

Hello everybody!

I wonder if anyone knows if encoding procedure for PDF /FlateDecode filter is compatable with zlib freeware library for decoding?
My problem is that generally everything decompresses fine, except for two things:
1. In some PDF files there are page contents streams that produce "corrupt data" zlib-errors.
2. Even more strange - for some reason zlib decompress routine substitutes two characters "Fi" with a single character with value 0xD1. This thing is persistent and happens on all occurencies of "Fi" substring.

Thanks a lot in advance,
Pavlo Barvinko
