Description nnn1590+libreoffice 2022-06-12 17:06:19 UTC
Character spacing setting is only applied to some characters when Japanese characters are used and grid (lines and characters) is enabled.

I tried with:
LibreOffice f82ddfca21ebc1e222a662a32b25c0c9d20169ee (LibreOffice-still.standard-x86_64.AppImage)
LibreOffice 30(Build:2) (APT-Sources: 
 http://ppa.launchpad.net/libreoffice/ppa/ubuntu focal/main amd64 Packages)

(I'm sorry if my English is wrong.)

Steps to Reproduce:
1. Open LibreOffice Writer
2. Open "Page Style" dialog
3. On the "Text Grid" tab, select "Grid (lines and characters)"
4. Click "OK" button (or press enter key)
5. Enter Japanese text (e.g., "ああああああああああああ")
6. Select some text and set character spacing

Actual Results:
The character spacing is applied to only a portion of the set area

Expected Results:
Applies to all parts of the set area

Reproducible: Always

User Profile Reset: Yes

OpenGL enabled: Yes

> 6. Select some text and set character spacing
In this step, on which dialog do you set the character spacing? Is it Format > Character > Position > Spacing?

For me, when I open your test document, select all, then changing the character spacing on Format > Character > Position > Spacing, none of the character spacing is changed. This is expected, as the page has Text Grid enabled and the paragraph has "Snap to text grid (if active)" enabled thus the characters should snap to text grids and any explicit character space setting is ignored by design.

To let the character spacing taken into effect, you need to disable text grid, or disable the "Snap to text grid (if active)" for this paragraph (select the paragraph and uncheck this option on Format > Paragraph > Alignment).

I set this to NEEDINFO and awaiting your clarify.

Well, I took a look of your screencast. You set the text grid, then selected a portion of the text and apply character spacing. The spacing was not shown, this is expected. Then you disabled the text grid, and then you see that the spacing are shown for that portion of the text you have applied spacing, this is also expected.

Am I missing something?
Comment 8 nnn1590+libreoffice 2022-11-28 04:01:33 UTC
Oh, I didn't know that.
I disabled "Snap to text grid (if active)" and the result is what I expected!
Thank you very much!
