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
