Convert CFF to FON

CFF, or Compact Font Format, is a file extension used in computer technology for efficient storage of font data. CFF was developed as part of Adobe's PostScript technology to streamline font file sizes while maintaining high-quality vector graphics. Its primary use is in embedded systems, print, and digital media, providing a compact and versatile format for typefaces. The history of CFF dates back to the early 1990s when it was introduced to address the need for more efficient font management in professional publishing and graphic design environments.

The FON file extension, part of the Windows Font Library, refers to a font library file used in Microsoft Windows 3.x. It is essentially an executable file renamed to FON, containing a collection of FNT files, which are bitmapped or stroked fonts. These files were used by applications to access system fonts. However, FON files are now obsolete, having been replaced by TrueType and OpenType fonts due to their limitations, such as the inability to resize fonts. The Microsoft Windows Font Viewer can open FON files.
