Created attachment 117140 [details] ODP presentation showing the issue When a line with text-direction Right-to-left starts with LTR characters the parentheses order is wrong. In the attached ODP both lines have text-direction Right-to-left. The first line starts with LTR characters which move the parentheses to the wrong position. The second line starts with RTL characters and the parentheses position is good. Tested with LO stable 4.4.4.3 and pre-release 5.0.0.2 on both Windows 7 and Ubuntu 14.04.

I'm no expert on RTL/LTR stuff but I see the issue. I'm not sure if it's "proper" to mix LTR and RTL the way the user is requesting to do. That being said I'm requesting Khaled's input here as he knows this stuff better than I do. @Khaled - sorry for the private poke but you mind confirming that this is an issue. Setting version to "inherited from OOo" as I've confirmed the "issue" on 3.3.
This does not look like an expected behaviour of applying bidi algorithm, so I think it is a bug.
@Joel, mixing English with RTL language like Hebrew or Arabic in the same line is common in presentations for higher education. For example, our use case is presentations in the area of Medicine and Biology that use the local language while the technical terms are in English.
Yes, it doesn't seem good, but at least there is a workaround. You should place the cursor right after the middle word בבב and go to Insert->Formatting Mark->Left-to-right mark. That's highly inconvenient (and buggy), but it's better than nothing.
Per Khaled's remarks - marking as NEW (confirmed) Minor - apparently there's a workaround which makes this minor; Low - default for minor bugs Note: The priority/severity doesn't dictate what gets fixed, it just is an objective way of classifying the bugs. If there is no workaround please set to Normal - Medium, else Minor is appropriate. Thanks!
I agree that while editing there is a workaround but we are using LO to convert PowerPoint presentations to PDF from the command line and this issue makes mixed lines in the output hard to read.

Comment on attachment 117140 [details] ODP presentation showing the issue Still an issue.
The same behavior is seen also in: Version: 6.0.0.0.alpha1+ Build ID: 6070dec9ca9a15587a2aece81f9ae1ab5ac0f8c4 CPU threads: 8; OS: Linux 4.9; UI render: default; VCL: gtk3; Locale: en-US (en_US.utf8); Calc: group (Build from 2017-Nov-05 00:00) OS: Debian 64bit Stretch (Debian 9.2, with some backported packages) However, I believe that it is not a bug. If I do at the beginning of the line starting with LTR character: Insert > Formatting Mark > Right-to-left mark Then the parenthesis order is right. In effect, the above makes the line start with a RTL character.
Omer, this is a bug. Try to load the attached PPTX in Impress and compare it to PowerPoint.
