Description Adolfo Jayme Barrientos 2015-05-19 21:57:59 UTC
It should, but only to maintain consistency with the rest of OS X applications and system.

To get the “UI-optimized” version of Helvetica Neue, it should be called with [NSFont systemFontOfSize:] as described here [1]. The font’s name, “Helvetica Neue”, should not be hardcoded anywhere.

Comment 1 Armin 2015-06-01 06:12:45 UTC
I can confirm this. LibreOffice on 10.10.3 (at least on my machine) uses Arial instead Helvetica Neue (see: Bug 91607).

I have also been experiencing this issue on OSX 10.11.4

It looks like LibreOffice is using Gill Sans Ultra Bold Regular for the active row and column, as well as the active sheet in the GUI.

The system font in newer versions of OS X is hidden and needs a special parameter to the font listing functions to show it. We don’t do that right now and end up not finding the requested font and use a fallback. We can’t also just pass that flag since it will make the font visible in the fonts drop down and we don’t want to do that, so we need to list the font internally but not show it in the fonts drop down.

This is still a huge problem for me. For some reason libreoffice is not just using some other font but a font that does not really exist, my UI just consists of rectangles... iMac late 2012, 10.13.2, Libreoffice
Comment 7 Kamei 2018-03-28 01:22:12 UTC
Me too.

And HarfBuzz of font layout system seem not to do font fallback.
As a result, some text is garbled like squares when LO doesn't use system font.

I think this is reproduced only Language Pack installed.

This bug still persists on macOS since it was reported (arguably before, if forum posts are accurate), and I can confirm at least through 10.14. Present in multiple LO versions since this issue was first reported, all the way up to The general response in fora etc has been #WORKSFORME.

The reason why this bug is only visible to some people and persists across LO versions and OS installs is that it turns out to be a particular implementation of the actual Gill Sans Ultra Bold font itself. (macOS ships with Gill Sans; the one attached was a different copy I found in ~/Library for some reason; I don't know where it came from.) If you disable it, the problem goes away. Why this is the case is probably worth investigating.
