Description Tofi 2014-11-04 10:56:27 UTC
A few days ago, after getting a new computer, I installed the newest version (4.3) and really loved the new design and changes you made to fit Yosemite BUT the right-to-left support is completely ruined - it is now impossible to combine numbers in a Hebrew text, as you cannot add a space between the text and numbers (same thing happens when trying to combine Latin letters as well). 
This has forced me to downgrade to 4.2.7 for better right-to-left-support.
Comment 1 Alex Thurgood 2014-11-10 15:26:59 UTC
Can not confirm on LO 4322, seems to work for me, but I don't really know what I'm supposed to be typing. If I type some hebrew text, the enter a space, type some numbers, enter another space, then some more text, the number is correctly separated by spaces.
Comment 2 Alex Thurgood 2014-11-10 15:28:59 UTC
For the moment this is worksforme. For those of us unfamiliar with rtl support please explain what we should see and what you actually see.

Test document

Document contains a few letters in Hebrew, followed by a space, followed by a few digits.

Good rendering in NeoOffice

I have attached a file, and screen shots of how it is rendered in LibreOffice and in NeoOffice.

The NeoOffice rendition is *correct* - the text is flush to the right, and there is a space between the text and the number.

The LibreOffice rendition is *incorrect* - the space somehow shifted to the right of the text, and the number is joined to the text.

* Version of LibreOffice on which this was produced:
* The font used in the example: Lucida Grande, which is supposed to exist
  on any Mac.
* MacOS X El-Capitan.
* NOTE THAT THIS IS A MAC-ONLY PROBLEM. Please make sure when you test it that
  you do so on a Mac, not on any other platform.
* This bug DOESN'T seem to be connected to #89034, which is multi-platform.

Please re-open this bug, and please put some effort into it, as the original poster said, this is a regression, LibreOffice used to work with Hebrew in the past, but this bug renders LibreOffice unusable with Hebrew on the Mac.

Can confirm this as well, marking as New and tagged with regression, I verified it worked correctly in

Bug 90778 is likely a duplicate of this bug.

Comment 8 eisa01 2016-09-11 14:06:35 UTC
I have triaged this down to regressing between version and, adding flag to request bibisect

It also applies to text in Calc documents, and likely the other components

Updating Summary with description from duplicate bug 90778 to better reflect actual bug

Adding Norbert to CC, could you possible take a look?

Hi, why is this resolved as fixed?
90778 and 92710 are resolved because they are marked as duplicates of this issue. I see no fix. And do get a mail from someone writing that right to left for Arabic is broken..

Khaled marked it as fixed: https://bugs.documentfoundation.org/show_activity.cgi?id=85852
I guess due to HarfBuzz.

Good rendering in LO 5.4

I can verify that this specific is fixed in current LibreOffice, the document renders as NeoOffice

For bug 92710 that also seems to work fine for me now.
Using the test case on this bug as the test document (as I'm not able to enable the RTL/LTR buttons in the toolbar), the spaces seem to behave well, not as in the video.

There might of course be other issues with RTL support
