No font for font marker symbol

[VxTedxV]

What is the bug or the crash? What were your expectations and what actually happened?

When displaying a standard label, QField uses custom font set in QGis or else default font from the device.
When displaying a font marker, QField acts like no default font is recognized.
When no font is recognized, letters appears with some symmetrical difference effect with holes.
QField shoud use default fonts available in the device instead of "no font" as it does for standard labelling.

Steps to reproduce the issue

Create a point layer (or other kind of layer with a point geometry generator) with a marker font symbology (geometry generator).
Apply a big size on marker to be able to see the effect more easily.
Avoid stroke that could mask the effect.

Version

4.2.11 Coral Sea (f7123fc)

Operating system name

Android

Operating system version

Android 16

Reinstall QField

• I have a fresh install of the latest QField version, but the problem persists.
• Problem can be reliably reproduced, doesn't happen randomly.
• Problem happens with all files and projects, not only some files or projects.

Additional context

When using QField on Windows, installed fonts are recognized and marker fonts are well displayed.
I have not tried to install custom font in QField folder. Installed fonts from the device should be recognized anyway.

@VxTedxV , is this an issue with QField, or a limitation in upstream QGIS on how it handles font markers?

I'd be happy to know how to answer that ! 😅 (can't run QGis on my mobile device to test !)
