This is a small utility to convert WOFF files to the OTF font format. It uses Python 3, so you need to have it installed in order to run it.
To run the script, simply invoke it from the command line:
./woff2otf.py font.woff font.otf
The first parameter is the source file (the WOFF) font, and the second parameter is the output file (in OTF format).
