 This is how I built custom fonts for [[https://github.com/olikraus/ucglib | Ucglib]]/[[https://github.com/olikraus/Ucglib_Arduino | Ucglib_Arduino]] on Linux. This is how I built custom fonts for [[https://github.com/olikraus/ucglib | Ucglib]]/[[https://github.com/olikraus/Ucglib_Arduino | Ucglib_Arduino]] on Linux.

 +The basic process involves:
 +  * Convering the OTF or TTF font to BDF format using ''otf2bdf'', ''gbdfed'', or ''fontforge''.
 +  * Using `bdconf` to convert the BDF format to C.
 +  * Adding the new code to the appropriate Ucglib file.
