FontForge for Windows is a tools for creating or editing TrueType fonts. I'm posting this because I needed a TrueType font called "C64 User Mono" for CBMTransfer to display the contents of a .D64 image. Style used to supply this font back in 2010, but has updated their release and the correct font is no longer available. I used this tool to edit the name and description embedded in the newer font so CBMTransfer could identify the right font.
This is a free / open-source editor that has a bit of a clunky interface, but at least it isn't crippled like the other crap TrueType font editors (read BirdFont sucks).
