utf-8 for RPL source code

[Helix]

So, if I understand correctly, you need 3 images, one for each font size: 5 pixels, 6 pixels and 7 pixels height. And of course, the same characters must be present in each font.

But a font with 5 pixel height is very small. Some characters will be impossible to draw at this scale ! Where these tiny characters will be used, only in the soft menus, or also in the stack?

It could be a tedious work, and I'm not ready to reinvent the wheel. I have found some examples of fonts here, but I'm not familiar with the copyright rules. For example, is a "creative commons attribution" OK for a starting point?
