Lack of fonts in the system?

[Zesko]

Did you install noto-fonts-emoji?

I solved my similar issue:

Weather icon fonts are missing in the KDE calendar widget

I added a webcal of meteomatics weather event to KDE Digital Clock widget (Default calendar widget) noto-fonts-emoji was installed, that should support many icon fonts of weather. But the screenshot shows some weather icons are rectangles. [Screenshot_20230317_103445] In my VM: [Screenshot_20230317_103412] I compared my VM and my system, both have the same noto-fonts-emoji and the same font configuration. I suspect a conflict with some fonts to override noto-fonts-emoji ?
