Current and expected situation

Please can you attach test file? Thank you.

A screenshot is attached. Isn't it possible to open it?

I believe raal is asking for a .odt document so that people not familiar with CTL text can try to reproduce this bug.

Or you can elaborate on your steps to reproduce:

...starting from enabling RTL mode (Tools > Options > Language Settings > Language, enable "Default Languages for Documents > Complex text layout", etc.), then how to switch to RTL mode, how to add a multi-level numbered list, how to make the numbering Arabic/Persian numbers, and so on.

The ODT file of reproduced situation

Please note that this file is produced for Farsi (Persian) language which is RTL same as Arabic

Created attachment 181202 [details]
The ODT file of reproduced situation

Also note that it is better to have a feature to change the "/" sign of multi-level numbering in Persian language. The "." character is more suitable but there is no option to change from "/" to "."

Hello Amin,

Unfortunately, your opening comment and your attachment "current and expected situation" - contradict.

In your opening comment, you've listed the "expected results" to the ordering of numbers that in your attachment is described as inappropriate/undesirable. You've also stated that's not what you get in LO.

Well, I'll assume that you mixed up "expected" and "actual" in the first comment.

Assuming that is the case, then - this is NOTABUG.

Numbers, in both Arabic and Hebrew (and most probably Farsi) are written from left-to-write, starting with the most significant decimal digit. They are _mostly_ read that way - with the exception that, in Arabic, the last two digits are read in reverse order. Anyway, 502 would be written, in Arabic with hindi digits as ٥٠٢ - both in an RTL and an LTR paragraph. Also, when writing a fractional number, the integral part is to the left of the fractional part.

It thus makes sense for Number-Dot-Number paragraph numbering, in Arabic as well as in English, to have the first number on the left, and the second number on the right. Hundreds of Thousands of Arabic speakers use LibreOffice, and - to my knowledge - have not complained about this being the order.

As for your ODT attachment #181202 [details] - when I open it, I see Arabic, not Hindi,  numerals in both sequences of paragraphs (i.e. 123, not ١٢٣). You should probably choose an explicit number sequence rather than sticking to the default.

So, please clarify and update the attachments if necessary.

Numbered lists (in Arabic at least) follow the hierarchical order not the LTR direction of the numbers, so 1 must precede 2 (i.e. be at the right of it).

One possible solution is to surround each level number with FSI (U+2068) / PDI (U+2069) so they becomes isolated from each other and follow the paragraph direction.

Hi Eyal,

About writing a simple number in Arabic or Farsi, yes, you are right; We write numbers from left to right BUT we are talking about numbered-list not integer number ;)

When we are writing a multi-level numbered list, we are not talking about decimal place or integer number, instead we are talking about a series of integer numbers which show the hierarchy in a list. We want to show that which item is children of which parent. So this is not a Number to follow the mathematics rules. this is a numbered list.

Please have a look at the attachment named "Wrong VS right situation" (https://bugs.documentfoundation.org/attachment.cgi?id=181746)

This problem is solved in Microsoft Word; In MS Word we can change the order of numbers.

Please note that this is the exact rule which is used in English ordered list and in Farsi (and I think in Arabic too) this rule is the same.

Also I agree with comment 9 (https://bugs.documentfoundation.org/show_bug.cgi?id=149824#c9) by "Khaled Hosny"

Yes. I agree.

Thanks for your attention. I searched but found nothing. My bad.
Anyway... I submitted a feature request to handle this situation and with guidance of @ajlittoz in Bug 158099 we found that if we could change intermediate characters in multilevel ordering numbers then we would put U+2013 EN DASH as intermediate character and the problem can be solved because this character or any similar characters hasn't neutral direction (as dot '.' is).

Is there any bug issue that requests this feature (change intermediate character in multilevel ordered lists)? I searched but found nothing. Shall I open one?
