It makes this job. I used it on a Mac with X11 and tried it on a VBox Ubuntu, but never tested it on a Windows machine with cgwin. You just have to open the font file and generate a new one using the correct type (here TrueType format).
If you need I can convert them for you and send them by PM's.
With this programm you can also modify the font file in order to have only lower case character, I thought it was Lyn or Pelim who tried to get lowercase typo for its UI, you just have to copy/paste lowercase to uppercase and it does the trick ;)
