Hi, I don't really get your point. This character   is clearly not the minus character - (apart that they don't actually look alike, just compare the codes, minus is 45, this one is 5760).

So nothing out of the ordinary that this special character is ignored by the JS engine. You can put it almost anywhere it will just toss it while processing the command. Hence, this works too

 $ ( "#result" ). append (2 +  40) ;
