WFN (font format)

WFN is a proprietary font file format used by early versions (v1 and v2) of CorelDRAW. WFN reportedly stands for "Wiffen".

WFNBOSS
CorelDRAW included a Windows utility named "WFNBOSS", which could convert WFN to a few other formats, such as Adobe Type 1. Some versions of it are said to have serious bugs. Here is a utility that claims to repair the bad PFB files it produces:
 * PFBFix

Software

 * Corel DRAW V1.21B → PROGRAMS.LZH → wfnboss.*
