Create and investigate PSF2 fonts
This utility is created with the aim of accelerating development of Linux PSF2 (framebuffer) fonts. It does not work with X fonts. The program can "explode" existing PSF2 fonts, creating an human-readable graphical representation of each glyph which can then be re-compiled into a PSF2 font. The project supports the use of unicode tables at the end of fonts, but currently (Dec, 2012) not fully (sequences are not supported), but this should be simple to amend.
