Extract the Unicode text information from PDF

Q: I have a pdf Text file with Unicode character in it.
Now I am using “ElementReaderAdvTest” (http://www.pdftron.com/
pdfnet/samplecode.html#ElementReaderAdv) logic to read Unicode.

To Read/ Extract the Unicode text information Do I need to have
same font family ( the Unicode font which is present in the pdf )
installed on my machine
A: No you don’t need any special fonts installed. If PDF has valid
Unicode mapping you could use ‘pdftron.PDF.TextExtractor’ to extract
text (please see http://www.pdftron.com/pdfnet/samplecode.html#TextExtract).

In case you need to get a Unicode string for a text-run element
(returned by ElemenReader) you can use element.GetTextString().
Alternatively if you need to map from the char_code in the
CharIterator you could use font.MapToUncide(char_code…) to map char
code to its Unicode representation.
