Dear community,

I try exrtact text from operator Tj. Now I have following case

(\000T\000E\000S\000T) Tj - in Adobe reader displayed as TEST.

In documentation from Adobe (PDF 32000-1:2008) I have not found description for this case. If content of Tj between '(' and ')', there are only examples with text, which not separated with '\000'. How can I know this case for extracting of text. Is there in anybody dictionary one element, which displayed, that all groups such as '\000' must be removed from content of Tj

thanks in advance

1. All literal strings are of the form described in 7.3.4.2, which says exactly what byte values must result in the string from escape sequences.

2. These are not separators, they will be part of the glpyh code.

3. It will be a multibyte font, probably a CID font.

4. In extracting text, you cannot in general just pick out the characters in brackets. This is hugely oversimplified, though often you are lucky. See 9.10, and make sure to follow it in detail.
