How can I change a font's family? I have 4 fonts belonging to the same family and I wish to separate them.
Also, I would also want to rename the font itself.
A simple file name change is not enough.
I'm looking for a free tool to do this, but came out empty handed after Googling a bit. All font studios seem to demand money.
I should specify that I need to do this in the operating system itself, so I need to modify the TTF/OTF/actual font file.
