iTextSharp embeded fonts issue when converting to text

It's obviously very easy to render text from PDF doc using PdfTextExtractor.GetTextFromPage. However when dealing with PDF created with embedded fonts I immediately stumbled into encoding issues.
Is there a generic method that will handle whatever font since i dont have any control on how pdf is created. My task is simple - convert pdf to text.
I've obviously searched for days before posting but could not find answer.
Thank you in advance!

Divide PDF Page using C#

I have A4 size PDF page. PDF page contains 10 images. I want to split the PDF page as 10 image files. Plz give me an Idea.
You can use PDFBox (a library available for .NET) to convert each page of the PDF to a PNG image, then use the GDI functions in C# to copy known regions of the PNG files and save them as individual image files. This only works if the layout of the images on each page is static.
More info on PDFBox:

PDFsharp seems to be a popular open source choice for PDF manipulation from .NET and Mono. PdfMod is a related Mono-based front-end.
