--- Comment #3 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Confirming on Windows 10 Pro 64-bit en-US with
Version: 6.0.1.1 (x64)
Build ID: 60bfb1526849283ce2491346ed2aa51c465abfe6
CPU threads: 4; OS: Windows 10.0; UI render: GL; 
Locale: en-US (en_US); Calc: CL

Text within Draw text boxes in Impress and Draw does not respond to ICU BiDi.

STR:

1. Install a font with coverage of Old Hungarian (10C80 - 10CFF) in the SMP.
2. Create a blank presentation in a Left-to-Right locale
3. create a new text box
4. type some text and select
5. context menu select Character dialog
6. select the font with Unicode 10C80-10CFF coverage
7. set language -> None
8. copy paste a sample Rovas string "𐲠𐳢𐳜𐳂𐳀𐳤𐳯𐳞𐳮𐳉𐳍"

Result -- Unicode BiDi from ICU libs are not invoked, like happens in Writer,
and string is rendered Left-to-Right. Shouldn't Draw/Impress be consistent with
the handling in Writer? Can the Draw/Impress Text objects be made so?

Work around, requiring multiple Draw Text boxes for layout, select text and use
the context menu Paragraph dialog. Set it to Right-to-Left.  This of course is
not optimal, as the RTL Rovas would normally be embedded into LTR paragraphs
containing Hungarian.
