Well, since we're talking about special characters: the ‘-’ that we find on our keyboard is a hyphen (U+002D). A minus sign is ‘−’ (U+2212) and is unlikely to be found on the keyboard unless it's a keyboard designed specifically for APL :-) -- \ “A ‘No’ uttered from deepest conviction is better and greater | `\ than a ‘Yes’ merely uttered to please, or what is worse, to | _o__) avoid trouble.” —Mahatma Gandhi | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list
