Reading through the thread I got motivated to play around with custom fonts as well. Now it seems like whenever I embolden any font (usually it seems like, if the style of a font works well with eInk the font is usually still too thin) the kerning goes out of whack. Of course the kerning itself does not change, but the proportionality somehow does. I attached two pictures of the Microsoft font Constantia as an example. Do you have the same problem when editing fonts and how do you deal with it or am i just imagining things?
