[GNC] Font problem

Looks like you took a detour down in the rabbit hole...

Sorry I’m not up on my locale foo. Maybe one of the devs familiar with locale issues can chime in, but I’d be surprised that locale choice is mangling a handful of lowercase glyphs.

I don’t think so because the gadgets throwing the errors are ‘header’, ’tabs’, and ’tab’ which are all part of parent widget GtkNotebook. Those are all part of the UI, not the Report content where the issue is. I also see similar warnings from time to time. I’d suspect it is an order of operations thing because those nodes do end up on the screen. (the gadget is called to be drawn and then the size specified after)

Again, a developer would have to chime in as I’m not versed in GTK or Fontconfig font handling, sorry.

This seems to be a bit of a detour. I’d still explore simpler, higher-level things first, like the fonts in the report stylesheets.
