Something of a typographic gift, this one, with 'x-height' being the method of measuring or specifying type. Why 'x'? Accordingly, a font's lower-case 'x' represents the average height of all the other characters. Excellent.
If you'd like the editable eps and use the character for your project, or smash it up and send me a copy back, mail me. It's rather chunky file-size to host. The edit's I'll feature here as a changelog to track its development.
