The minim symbol is an m with a long tail on its lower right, crossed by an x. In Unicode, it's combined with the Scorpio astrological sign and, on Macs, that is inexplicably forced into a disgusting emoji-style icon even in plain running text.
The symbol itself is an English or language question but, since I'm curious about how to format the CSS or HTML to force my Mac to display it in a less obnoxious form, I suppose it's really a question for one of the computing subs. But which one is appropriate? Any idea?
