I borrowed your idea and made something short and very ugly which does the whole job including percentages and total. I even added a count of distinct characters: 
++$t,++$c{$_}for map/\w/g,<>;
print$_,"\t",$c{$_},"\t",$c{$_}/$t*100,$/for sort keys %c;
print"Distinct: ".keys(%c)."\tTotal: $t\n";

I doubt I'd call that an "improvement", at least with a straight face. It could be cleaned up pretty easily, though.

    Then do it! No good leaving lousy code floating around... ;-)

      But... but... it's golf! ;-)

      I guess adding a feature's not exactly in the spirit of golf, though. More golfed: 

      ++$t,++$c{$_}for map/\w/g,<>;
print$_,' ',$c{$_},' ',$c{$_}/$t*100,$/for sort keys%c;
print"Total: $t\n"

      So now that that's out of the way, how about still short but somewhat easier to read? 

      ++$t, ++$c{$_} for map /\w/g, <>;
for ( sort keys %c ) {
    $p = sprintf '%3.2f', $c{$_} / $t * 100;
    printf "%-5s%5d%7s%%\n", $_, $c{$_}, $p;
}
print 'Distinct: ' . (scalar keys %c) . "\tTotal: $t\n"
