State: closed
Merged: Yes

Summary of the Pull Request

Adds fallback routine for when a font name is missing instead of crashing due to uncaught exception thrown when font cannot be found.

PR Checklist

Detailed Description of the Pull Request / Additional comments

For GDI and for DirectX using the stock Layouts and Formats, if your chosen font face name isn't found... something else is just picked on your behalf. When I wrote our custom DX code, I instead threw an exception when I couldn't find the chosen font face. That exception was uncaught and led to a crash.

I decided to just make the custom code act more like the stock code and attempt to choose a fallback if we cannot find what you've requested. I also improved a bit of the passing around of the chosen font name and added locale name information while I was at it.

Validation Steps Performed

  • Opened settings
  • Set font name to "arse"
  • Watched as nothing changed from previous Consolas selection
  • Closed application
  • Relaunched
  • Didn't crash this time, it just chose Consolas instead
