Custom fonts are not displayed properly on MacOS

Babiole

Hello,

I'm currently experiencing an issue with the load of font.

Here is the result on windows :

As you can see the fonts are well loaded (it's also works on ubuntu 17). The fonts are used as icons.

This is the result on MacOs :

The fonts are loaded like this :

const auto id = QFontDatabase::addApplicationFont(":/resources/fonts/Font Awesome 5 Free-Solid-900.otf");
const auto id1 = QFontDatabase::addApplicationFont(":/resources/fonts/Font Awesome 5 Free-Regular-400.otf");
const auto id2 = QFontDatabase::addApplicationFont(":/resources/fonts/Font Awesome 5 Brands-Regular-400.otf");
qDebug() << QFontDatabase::applicationFontFamilies(id).at(0);
qDebug() << QFontDatabase::applicationFontFamilies(id1).at(0);
qDebug() << QFontDatabase::applicationFontFamilies(id2).at(0);

This is the ouput result on windows :

"Font Awesome 5 Free Solid"
"Font Awesome 5 Free Regular"
"Font Awesome 5 Brands Regular"

And, the mac output :

"Font Awesome 5 Free"
"Font Awesome 5 Free"
"Font Awesome 5 Brands"

I see the Note on https://doc.qt.io/qt-5/qfontdatabase.html#addApplicationFont :
Note: Adding application fonts on Unix/X11 platforms without fontconfig is currently not supported.

I installed qt 5.10 through the Qt Installer, so i don't know if the installer version contain fontconfig, but it's works well on Ubuntu with the Qt installer.
Do I need to reinstall Qt from sources with -fontconfig or something like that?
Do you have any idea of what could be wrong?

Hi
Did you try the Font Awesome 5 font in another macOs application ?
Oddly the icon you get looks like when some unicode string is not decoded properly.

Thank you for your quick answer!
I just tried to create a new application, the same bug occurs. However, if I write "Font Awesome 5 Free" instead "Font Awesome 5 Free Solid" in my qml, it works.
So, I can fix my application with a define to check on which system I am, but it's still strange that the name is not the same on each plateform.
Because you have to use the font name in the qml :
This works on windows / Ubuntu

Label {
    text: qsTr("\uf039")
    font.family: "Font Awesome 5 Free Solid"
    font.pointSize: 40
}

This only works on MacOs

Label {
    text: qsTr("\uf039")
    font.family: "Font Awesome 5 Free"
    font.pointSize: 40
}

The second issue, is that i can't recognize these two fonts on MacOs:

"Font Awesome 5 Free Solid"
"Font Awesome 5 Free Regular"

Because both return :

"Font Awesome 5 Free"

Anyway, I think I can fix my application even if the behavior seems odd, should I create a bug report to have a record of this issue?

I just started using Font Awesome as well, and stumbled upon this forum post. Now I wonder if I will have this issue on iOS? Have you tried? Or have you figured out something new?
