SUMMARY Demonstrative video: https://youtu.be/zIm4MYzdj4o The default Konsole font doesn't work well with braille. The unlit dots are just a fainter shade of white which makes differentiating the characters very hard. I used ascii-image-converter in the video, but this also affects tools like btop which uses braille to display graphs. It is next to impossible to make heads or tails of btop with the default font STEPS TO REPRODUCE 1. Open a console program that uses braille OBSERVED RESULT The characters are not differentiable EXPECTED RESULT Some saner font should be used SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.4.4 KDE Frameworks Version: 6.17.0 Qt Version: 6.10.0 Kernel Version: 6.16.0-arch2-1 (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i7-7600U CPU @ 2.80GHz Memory: 24 GiB of RAM (23.2 GiB usable) Graphics Processor: Intel® HD Graphics 620 Manufacturer: LENOVO Product Name: 20HG0003SG System Version: ThinkPad T470s
The default font is the default one from Plasma (if started in Plasma). I agree that after X years we might want to switch the default.
Braille is intended to be three dimensional, so you can feel it; it's not really a "font" intended for on-screen display. If it's being used as such, that's not really a supported thing, and amounts to a clever hack. If there is a problem with the font itself, that needs to be reported to https://github.com/source-foundry/Hack/issues
Last commit to Hack was 5 years ago. I don't think anything will change by reporting to them. It would be easier to change the default font.
Perhaps it would, but that's a separate discussion. It wouldn't make sense to change the default monospace font for this specific hack of using Braille to display non-Sixel imagery in Konsole. If we change the default monospace font, it should be because we like the new one better for normal use in text editors and terminals.
