PDFsharp & MigraDoc Foundation

hi!

PdfSharp is a very cool library but I have a problem about extracting texts. PDF reference explain this : "Strings may also be written in hexadecimal form".
I get some hexadecimal form after extracting texts but these datas are differents of original text.

For exemple :
My PDF contains "Ajout d’une langue à un projet." and when i extract texts with PdfSharp, i get this : "00040169017D01B5019A0003011A035B01B50176011E0003016F01020176015001B5011E00030103000301B5017600030189018C017D0169011E019A0358".
I can't find the original text. Indeed when I convert this to ASCII, it gives me "
i
}
µ
š
[
µ
v

o

v
P
µ


µ
v
‰
Œ
}
i

šX" which is totaly different compared the original text..


Does anyone have any clue what is the issue and how to fix it?

Thanks beforehand for your reply!

Hi!

PDF files often contain a subset of Unicode fonts and there should be a mapping table that allows you to translate the indexes from the hex string to the Unicode values.
Can you copy the text to the clipboard using Adobe Reader?

Yes I can copy the text to the clipboard using Adobe Reader.

I finaly found the mapping table! I just have to use it to convert the hexa form.

Thanks for your answer, it helped me
