How to convert Bitmap Font to OpenType Bitmap Font
In Fedora 31, pango is upgraded to 1.44 and switch to use harfbuzz.
In order to continue to use bitmap font with pango, please use the fonttosfnt tool to convert the font.
Details
Please install the latest package xorg-x11-font-utils and freetype-demos in Fedora 31.
We will use some python script to help the conversion.

Here are two ways to convert the fonts:
1. Convert one BDF/PCF font to one OTB font
2. Combine the BDF/PCF fonts into one OTB font with the same family and style name
Currently we prefer the second method, but sometimes it will make the bitmap font not monospaced; if this problem happens, please try the first method.
Take the Terminus font as example
Steps
1. Install fonttosfnt from the below Fedora copr
URL: https://copr.fedorainfracloud.org/coprs/pwu/fonttosfnt/
2. Convert the font with fonttosfnt
$ fonttosfnt -b -c -g 2 -m 2 -o terminusn.otb ../terminus-fonts/ter-*n.pcf.gz
$ fonttosfnt -b -c -g 2 -m 2 -o terminusb.otb ../terminus-fonts/ter-*b.pcf.gz
3. remove the terminus-fonts package and install the terminusn.otb and terminusb.otb fonts
4. re-login the desktop and use the "Terminus" font
