Thank you, it's more descriptive now.

Contrarily, this branch's Unicode support seems to be a regression from
the main line's. All characters not within US-ASCII are being displayed
as question marks in my terminal emulator. Running "M-x
universal-argument <RET>" followed by "M-x what-cursor-position <RET>"
reveals that Emacs thinks that these characters are "not encodable."
Therefore, they do not have terminal codes.

Sorry, I do not. My knowledge of fonts is limited.
