Preamble: Charis is a free font from SIL and legally based on Charter. More info: http://scripts.sil.org/CharisSILfont
I've been using Charis for some time now and every once a while I adjust it some more to my liking. I know that some you did your own modifications (e.g. Charles Ellertson, Richard Fink), are you willing to share your version of the font?
To set a good example, here is my version – unoriginally renamed to “Charta” (German for “charter”) since modified versions must be renamed according to the SIL license.
What I changed (as far as I remember):
- Added kerning
- Respaced the italics (Charis' italics are too tight, in my opinion)
- Slightly emboldened the superscript numbers
