I couldn't seem to find an appropriate answer to this question on google.
I'm planning a project about "phonetic spelling". So I need a font that has all those diacritics and whatever glyphs a phonetic-spelling font has to have. The question that came up is if it is actually "allowed" to just buy a font family and build (alter) my own custom version of it for the phonetic alphabet?
Is this legally ok? Thinking about the process I'm just thinking of buying a suited font for the project and alter it in Fontlab or Glyhps (or whatever comes in handy) and create my own custom version of it.
I guess a consequent question is where do I use this font, right?
The project is going to be a book later. And if it is possible the the font should also be available as a download.
The reason the font should also be downloaded is that this book project is part of a greater regional project that is about phonetic spelling and it would of course be good if the custom-made font (which is probably a lot of work) is also available later for other uses.
Can you please fill me in with some details about that matter. What is possible and what not?
Would it for instance be possible to sell this custom font afterwards that is based on top of an already existing font? I guess not.
Thank you for your tips and answers.
