Description gk.lo.b5gz3ll1 2025-05-22 21:34:00 UTC
Description:
All non-ASCII characters are displayed as empty rectangles in the "Notes" section in the "Presenter Console" (see "LO3….jpg").

The presentation is old, but changed from time to time. The problem appeared after an LibreOffice update this year and since then, all presentations are affected. I add more technical information below.

In this presentation (see "Lektion….odp"), the used font is not installed any more, but MacOS provides a replacement font (see "LO1….jpg" on the left side).

Using other fonts for the Notes' text does not help. Neither when formatting the Notes' text directly, nor when changing the font in the Style "Notes".

It does not matter, if editing the Notes using "View"→"Views Tab Bar"→"Notes", or the new "View"→"Notes Pane".

Some more errors, maybe related, are:

The (old) Font name is not displayed in the font selector (see "LO1….jpg"). However, the font name is selectable with the mouse, can be copied, and pasted in a different programm (see "LO2….jpg").

The "Animation" view is not diplaying the non-ASCII characters, which are displayed on the Slide itself (see "LO4….jpg").

Steps to Reproduce:
1. Open the attached presentation on an intel-x86 based Mac.
2. Start the Slide Show with a Presenter Console.
3. Open the Notes view in the Presenter Console.

Actual Results:
All non-ASCII characters are displayed as empty rectangles. All other character are displayed normally.

Expected Results:
All characters are displayed.


Reproducible: Always


User Profile Reset: Yes

All these errors appear with:

The errors do NOT appear on an Apple Sillicon Mac!

The errors do NOT appear in other software on that intel-x86 Mac.

Deleting LibreOffice and all settings in "~/Library/…" does not help.

Reinstalling MacOS does not help.

LO1 font name in font selector seems to be empty

Right hand side, on top: the font name selector seems to be empty.

Left hand side, on the bottom: the selected font, which is not available on the Mac, got a replacement by MacOS.

LO2 font name invisible, but copy&paste it works

The dialog for the format does not show the font name, but shows empty rectangles after selecting the font name with the mouse for copy&paste.

The font name can be pasted into another Mac software (TextEdit).

LO4 Animation details do not show the animated texts' non-ASCII characters

The Animation overview also shows non-ASCII characters as empty rectangles.

However, these characters are shown on the slide itself.

Thank you for reporting the bug. I can not reproduce the bug in either of the versions of LibreOffice listed below. I'm using an Intel-based Mac and I'm able to see the non-ASCII characters displaying properly.

Comment 9 Saburo 2025-05-31 02:59:11 UTC
I think it is due to a font called 'tofu' related to issues with the Japanese language.

By the way, is it possible to change the Sans font used in the presenter console in LibreOffice?
Do you know anyone?
Comment 10 gk.lo.b5gz3ll1 2025-05-31 13:16:15 UTC
Problem solved, it is NOT a LibreOffice bug:

I searched for information about how to configure LibreOffice's UI, and found "LibreOffice"→"Preferences…": "LibreOffice"→"Advanced"→"Open Expert Configuration": "Expert Configuration". After searching for "font" in "Preference Name", Chinese characters are not displayed here as expected, but Korean characters are displayed (see "LO6….png").

I then checked the font names configured for Chinese "UI_SANS". From the ones having latin names, most are not available on my Mac, or did not contain Chinese characters. But "PingFang SC" is available and does contain Chinese characters, but was uninistalled on my wife's Mac (unknown why, when, by whom, because "PingFang HK", "PingFang MO" and "PingFang TC" are istalled!).

After reinstalling "PingFang SC" and restarting LibreOffice, Chinese characters are displayed in dialogs and in the "Presenter Console" normally again.

@Saburo: The "UI_SANS" font names are used for the "Presenter Console", too.

So it is not an LibreOffice bug, but it was "just" a missing font.

Thank you for trying to reproduce the error!
