I created my own font in bdf format and then converted them with bdf_2_phf.
Install the font with fontcfg. Use ped to test the font and all is well.
The problem is if the photon is stop and restarted the font aren’t working
anymore although they will show as installed in fontcfg. Uninstall and
reinstall them cures the problem.
traceinfo show this however: “Error EOK load font phfontXX started OK - EOK”
Error EOK, that’s kinda weird
