 (notable case is Pango 1.44 dropped support for FreeType in favor of HarfBuzz),
 so you might not see bitmap fonts in some applications.
 
+There's a method to build OTB (open-type bitmap) font from BDF with `fonttosfnt`.
+The `opentype` target converts all fonts to OTB.
+
+Also conversion to PCF is possible make target `pcf` does this thing to all
+fonts by calling `bdftopsf` utility.

+Original inctruction: https://fedoraproject.org/wiki/BitmapFontConversion

 16x8 font can be installed in Linux console.
 First, convert BDF to PSF (bdf2psf utility needed for this).
 `make psf` command will do conversion for you.
