Description yousifjkadom 2018-03-01 20:23:35 UTC
Hi. I tried "export to EPUB" new functionality on office document in Arabic language. 

Frankly speaking, I was expecting a rubbish symbols of unknown meaning .....

But, output EPUB file was beyond my imagination: Arabic contents displayed correctly BUT with only one defect: alignment & direction of sentances is to the left (from left to right).

Please notice when I said direction is from left to right I do not mean that words rearrange inversely. But, I mean that character like "!" at the end of the line will appear in EPUB at the beginning of the line.

Please compare attached files (original office & EPUB)

Hi, thanks for the bug report!
Confirmed using LO 6.1 master build (bc6f3c0fe95f9162fb14dc540fa2b4bc81af32bf) / Windows 7.

Hi. I test bug on version 6.1.3.2 LO as AppImage. It is still existing without any improvement.

Looks like it is related with the styles/language export I mentioned in bug 121449.

I'm comparing again outputs from both filters for additional information.

Style sheet from L 6.2 native epub filter

Writer2html 1.6.1 (it has it's own bugs like the style sheet not formatting properly contrary to the native epub)
  <body dir="rtl">

I'm copying Mark and Miklos, which I understand are involved in epub filter.

Thanks for rechecking! Please also add version information from Help -> About, so the version can be known without having to look up which AppImage was current at the time.
Comment 9 yousifjkadom 2019-11-18 06:39:01 UTC
Last available fresh standard AppImage is version 6.3.3.2

Hello. I tested this issue on LibreOffice version 7.4.0.3 (flatpak version from FlatHub). 

Unfortunately, it is still existing without any fix or improvement!

I will change the version in this issue from 6.0.2.1 into 7.4.0.3.

I'm sorry to say, there are not many developers on this project relative to its size and complexity.

The version field is for the earliest known version in which the issue is present, NOT the most recent known version. We don't need the most recent known version because if the Status is NEW then the bug is presumed to be still be present in every version since the one it was discovered in. 

You can find descriptions for every Bug Field here:
https://bugs.documentfoundation.org/page.cgi?id=fields.html

I have reset the version field to 6.0.2.1.
