Hello kabucek:
The problem you meet is a common problem, It is caused by embed soft
font use non-standard encoding(Custom Encoding).Normally PDF Type 3
Embed Font like to use Non-Standard encoding. Adobe PDF reader use
three methods to recognize the text in PDF files: either use ToUnicode
dictionary associate with the Embed soft font or check if the character
use standard encoding, or check if the character use a standard
character name , If the characters have no ToUnicode
dictionary and it uses non-standard character encoding and use non
standard character name, then there is no way to figure out which
character code it is without using OCR plug-in module to scan the
character bitmap.
Solution: You need a PDF converter with OCR plug-in module.
