[Issue] Unicode character causes display distortion

[Peter5004]

I first brought this up in a thread some months ago (now locked) but didn't get a full resolution. But now I have more information which may enable someone else to replicate the problem. I'm not seeking a solution urgently but I'd like to draw attention to this.

Edit: Peter5004 refers to Justified text extends beyond margins

Appearance: justified text display corrupted and spills over margins:


Criteria:

• Text contains one or more 'unusual' characters. In this case one of the alternative asterisks ∗ (Unicode U+2217) which is seen surrounding the first "quick"; the problem also occurs with U+2216 but not with U+2215.
• Main body of text is 18 point or larger, but some text at different size. In the example the extra line feed between paragraphs 2 and 3 is 16 point.
• Occurs with both Times New Roman and Arial - but may happen with other font types.
• OO version 4.1.15 (I understand this is latest version). Windows 10 Home version 2009.

I should explain that I first saw the problem in text copied-and-pasted from elsewhere. I don't use that particular Unicode asterisk myself.

I can see the problems in OO, not fixed by updating, fixed by removing the asterisks and saving and reloading.

In LibreOffice the file seems to be okay,

There looks to be a fiddly workaround in OO of putting the character in a drawing textbox.

File was OK for me using Xubuntu 22.04.5 LTS. and AOO 4.1.15. It might be a graphics driver problem.

Displayed correctly with OpenOffice 4.1.7 on MacOS 13.7.6. Perhaps it is a Windows-only problem.

Perhaps it is a Windows-only problem.

Win 10 prof, AOO 4.1.15 portable:

I suppose that is a graphics driver problem.

I see (sometimes) the problem with AOO 4.1.15 / AOO 4.1.15 portable on Windows 7, 10 and 11.

Windows Character Map utility does not show U+2216 and U+2217 for Times New Roman and Arial.
In AOO, U+2216 and U+2217 are not listed in Insert ⟶ Special Characters for these fonts. I have no idea it has a bearing on matter at hand.

Anyway, have you tried any other font that supports U+2217?

[Peter5004]

Thanks for the replies. I can see it's not just me with the problem, which is reassuring. And I can work around it by simply substituting alternative characters which don't cause this effect, like the 'normal' asterisk (U+002A). The problem doesn't occur in LibreOffice, as mentioned above.

Nevertheless it would be good to get the Apache wizards to look into this matter - if there were a way of notifying them. I found a site called "AOO bugzilla" but can't access it since I don't appear to be an 'authenticated' user. Perhaps someone else can?

If you managed at all to file a bug report you likely would still be waiting at the death end of the universe for a fix. Best switch to LibreOffice. There are several good reasons for making the switch anyway, some of which are mentioned here: [Tutorial] Considering a Switch from OpenOffice to LibreOffice? Some Useful Information

Bug reported: Issue 128613 ("High-numbered Unicode character causes display distortion when editing")

This has been observed when U+2217 (an alternative asterisk) or U+2216 (alternative backslash) present in text. Other high-number Unicodes (e.g. U+2215) don't cause this problem.

In the example, all text *except* linefeed after 2nd paragraph is 18pt Arial or Times New Roman - Justified (other fonts not tested). Linefeed is 16pt (this makes a difference).

Screen grab attached.
