----------------------------------------------------------------
In ISO 32000-2:2020 *q* and *Q* became general graphics state operators while
in ISO 32000-2:2017 they still were special graphics state operators.
Furthermore, ISO 32000-2:2020 section 9.4.1 now requires
{quote}When the graphics state stack operators *q* and *Q* (see 8.4.2,
"Graphics state stack") are combined with
the text object operators *BT* and *ET*, each pair of matching operators (*q* …
*Q*) shall be properly
(separately) nested.{quote}
In particular, therefore, this issue should be labeled {{PDF2.0}}.

> Key: PDFBOX-5359
> URL: https://issues.apache.org/jira/browse/PDFBOX-5359
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing, Rendering
> Affects Versions: 2.0.24, 3.0.0 PDFBox
> Reporter: Jaromír Dobrý
> Priority: Major
> Attachments: zapf_dingbats.pdf, zapf_dingbats_page_indirect.pdf
>
>
> Open the attached file in PDFDebugger and compare to the Adobe Reader or
> Foxit. The problem is in saving/restoring the graphics state inside text
> object (which should be allowed according to the documentation and text
> matrices should be part of the graphics state).
> Therefore I propose the solution to move PDFStreamEngine.textMatrix and
> PDFStreamEngine.textLineMatrix into PDGraphicsState.
