The provided BDF files are encoded as CP1252, but they claim to be ISO8859-1. This causes a few glyphs (like `œ`) to be unused. Use fontforge to re-encode from CP1252 to Unicode, but keep doing the conversion with other tools because fontforge introduces spacing issues.

Dina is a monospace bitmap font, primarily aimed at programmers. It is
|
|
relatively compact to allow a lot of code on screen, while (hopefully)
|
|
clear enough to remain readable even at high resolutions.
