replacetag

   I am looking for a way to replace text in my pdf file which was not created by quick pdf library.I tried ReplaceTag function but it works with weird way. When I run code:
$oQP.ReplaceTag('Z!CD!', ' ')
then text 'MARTA" will be changed to space
Z stansd for M
! stands for A
C stands for T

Now when I use this code:
$oQP.GetPageText(3)
then I can see 'MARTA' text normally

I also tried:
$oQP.ReplaceTag('Z!CD!', 'MARTA')
and now instead of 'MARTA' text I see '1EB7E' text 

Is it something about encoding?

	The text content CAN be visible but it's not a must - there are several technics to integrate text.

	I mean I can replace text on my pdf but A letter does not match A. Why is that?

	What you see and how it's embedded into the content is different. Here you can read about the file type pdf in common and how information is integrated in a pdf-file: https://en.wikipedia.org/wiki/PDF Regarding strings inside of pdf content you can read this: Strings, enclosed within parentheses (`(...)`) or represented as hexadecimal within single angle brackets (`<...>`). Strings may contain 8-bit characters.
