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.

Confirmed in Versión: 6.2.0.0.alpha1 (x64)
Id. de compilación: ff46ad24d1d3cbcea45895520483ed1fd4ff488b

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.

LO6.2 
<body class="body0" xmlns:epub="http://www.idpf.org/2007/ops">
<p class="para0"><span class="span0">تحية طيبة !</span></p>

</body>

Style sheet from L 6.2 native epub filter
.para0 {
  line-height: 150.0000%;
  margin:  0px 0px 0px 0px;
  text-align: justify;
}

.span0 {
  font-family: 'Arial';
  font-size: 16.0000pt;
}

.body0 {
  -epub-writing-mode: horizontal-tb;
  -webkit-writing-mode: horizontal-tb;
  direction: ltr;
  writing-mode: horizontal-tb;
}



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">
    <p class="Standard" dir="rtl" style="text-align:justify">تحية طيبة !</p>
    <p class="Standard" dir="rtl" style="text-align:justify">احي فريق تطوير برنامج ليبري اوفس لجهودهم الجبارة في تطوير هذا البرنامج المجاني المفتوح المصدر واتمنى لهم التوفيق في جهودهم الجبارة لما فيه فائدة &#160;المجتمع.</p>
</body>


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
