            Bug ID: 133067
           Summary: Wrapped RTL text characters within shapes are exported
                    to tagged PDF with incorrect character order
           Product: LibreOffice
           Version: 6.3.5.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: zainab.ali at blackboard.com

Description:
Wrapped RTL text characters within shapes are exported to tagged PDF with
incorrect character order.

The attached pptx file contains RTL text within a shape.  The shape has "Word
wrap in text shape" set to true.
Exporting the pptx as a tagged PDF should result in the same order of
characters regardless of whether word wrap is enabled or not.


Steps to Reproduce:
1. Export the pptx as a tagged PDF using  File > Export as > Export as PDF >
Tagged PDF
2. Select the text within the shape and disable word wrap using Format > Object
and Shape > Text > untick Word wrap in text shape 
3. Export the pptx again as a tagged PDF using  File > Export as > Export as
PDF > Tagged PDF


Actual Results:
The codepoints of the unicode characters within the marked content sequence of
the PDF with wrapped text are in the following order:
1579 1578 1576 1575 32 1582 1581 1580 

The codepoints of the unicode characters within the marked content sequence of
the PDF with no wrap are in the expected order.


Expected Results:
The codepoints of the unicode characters within the marked content sequence of
both PDFs should be in the following order:
1582 1581 1580 32 1579 1578 1576 1575


Reproducible: Always


User Profile Reset: No
