I'm re-constructing a font, and I'm wondering if there's an option to increase the width of specific characters. For instance, increase the width of the full stop/period character by 1 pixel. In the image below, the top grey text is what I'm trying to achieve, while the white text is the resulting font from pixelfont.

Right now you could post-fix your font using FontForge

I want to make the kerning pairs into a larger editor where you can do something like

. * 1

to increase spacing between . and any other glyph, but I’m currently drowning in work tasks, so it might take a bit

When you do that, please make sure that it is still possible to specify spacing between a full stop and an asterisk. :)
