dina-font: fix encoding

Browse source 
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.
