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.

## 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:
