Beginning from PaintCAD 2.1 version - you can disassemble PCF-fonts to separated BMP-symbols (as GIF-animations on separated GIF-frames), edit these BMP-symbols as picture, and assemble to new PCF-file. For assembling/disassembling PCF-fonts you can use commands '0'-'Fonts'-'Pack font' and '0'-'Fonts'-'Unpack font'.
