5fef99c641 fix: render U+FFFD replacement character instead of ? (#366)
The current behavior of rendering `?` for an unknown Unicode character
can be hard to distinguish from a typo. Use the standard Unicode
"replacement character" instead, that's what it's designed for:

https://en.wikipedia.org/wiki/Specials_(Unicode_block)

I'm making this PR as a draft because I'm not sure I did everything that
was needed to change the character set covered by the fonts. Running
that script is in its own commit. If this is proper, I'll rebase/squash
into one commit and un-draft.

bf7bffd506 Aleo, Noto Sans, Open Dyslexic fonts (#163)
## Summary

* Swap out Bookerly font due to licensing issues, replace default font
with Aleo
* I did a bunch of searching around for a nice replacement font, and
this trumped several other like Literata, Merriwether, Vollkorn, etc
* Add Noto Sans, and Open Dyslexic as font options
  * They can be selected in the settings screen
* Add font size options (Small, Medium, Large, Extra Large)
  * Adjustable in settings
* Swap out uses of reader font in headings and replaced with slightly
larger Ubuntu font
* Replaced PixelArial14 font as it was difficult to track down, replace
with Space Grotesk
* Remove auto formatting on generated font files
* Massively speeds up formatting step now that there is a lot more CPP
font source
* Include fonts with their licenses in the repo

## Additional Context

Line compression setting will follow

5e1694748c Fix font readability by expanding blacks and trimming whites (#55)
## Summary

* Previously, only pure black pixels in the font were marked as black,
this expands the black range, and makes the lightest pixels white

## Additional Context

* Noticed personally it was kind of "thin" and washed out a bit, this
massively helps, should also address concerns raised here:
