Nevertheless, if we see Adobe behavior, it doesn’t even allow you to change the text when MyriadPro font is not installed and is removed from Adobe’s Resources installation folder. So Adobe uses the font because it ships the font during Adobe’s installation. The font it must be installed to allow us to use it and its a requirement to make possible to reuse the font.
2) when I have Tags right side aligned and i replace them, they shift to the right. How can I take care that the alignment is as it is in the source pdf?
The Pdf format doesn’t have any information that the tags are right-aligned. So you must manually perform the fragments alignment changing their coordinates. Please use following code snippet that performs the right alignment and works fine when font is installed on the system (Please take a look over attached 34711-installedFont.pdf file):
[C#]

all instances of the input search phrase

//accept the absorber for all the pages
pdfDocument.Pages.Accept(textFragmentAbsorber);
TextFragment fragment1 = null;
TextFragment fragment2 = null;
TextFragment fragment3 = null;
//get the extracted text fragments

textFragmentAbsorber.TextFragments;
//loop through the fragments

textFragment in textFragmentCollection)
