To display utf8 characters on all vt console I did following settings. 1. Download GNU Unifont BDF file (http://unifoundry.com/pub/unifont/unifont-13.0.05/font-builds/unifont-13.0.05.bdf.gz) 2. gunzip unifont-13.0.05.bdf.gz 3. vtfontcvt unifont-13.0.05.bdf unifont.fnt 4. cp unifont.fnt /usr/share/vt/fonts 5. Add 'allscreens_flags="-f 8x16 unifont.fnt"' to /etc/rc.conf 6. Add 'hw.vga.textmode=0' to /boot/loader.conf.local 7. shutdown -r now On 12.2-RELEASE and 11.4-RELEASE it works as is expected. But on 14-CURRENT(man) and 13.0-ALPHA3(stable/13) it result in kernel panic.

At this time, we also must set refcount 1, and refcount will get incremented in cnprobe() callback. At some point the memory allocator will be available, and we will set up properly allocated font data, but we should not disturb the refcount.

As we get started with no memory allocator, we set up static font data for font passed by loader (if there is any). At this time, we also must set refcount 1, and refcount will get incremented in cnprobe() callback.
