The title is self-explanatory really, all I really want to do is be able to add some kind of notch to any character, so that they are visible if you are actively looking for them.
Like accents, but less obvious and more customizable.
David Carlisle asked about what kind of notch I was talking, I was thinking something like:
Either would work, but I would prefer something like the first one.
More specifically working with the cedilla thing, I would cut off the round part, keep the square at the top and move it up and to the right, but still such that it would be connected wih it.
