What special characters do most smart phones have?

I am creating a log in system for my website. I need to know what symbol/special characters are easily accessible to most smart phones and what symbol/special characters are not so easily accessible. I realize there are lots of different phones but I want to know what symbols I can likely count on being there most.

Keep in mind a standard desktop keyboard is limited to this list, and so is my programming:
~ ` ! @ # $ % ^ & * ( ) _ - + = { } [ ] | \ / : ; , . " ' < >  ?

I don't have a smart phone so I am guessing they are limited to ! @ # + - and if you want more you have to digg into the operating system to find them. Anyone with a smart phone should be able to tell me what symbols are in plain sight or easily found. Thanks.

Your Android has a lot more than I thought. I am going to assume most cell phones have at least 5 accessible special characters.

I notice you are living in Australia. I have one off topic question for you if your game. This is no joke, I am actually curious. Yesterday I watched a little news video from msn.com that claimed water in the southern hemisphere (south of the equator) flows down the drain no differently than in the northern hemisphere. They said the Coriolis force was too weak to have an effect. It was my understanding most of my life that because of the Coriolis force, water drains down a toilet for example (and I verified this in my home) counter clockwise in the northern hemisphere, the same direction hurricanes and tornadoes turn in the north and water drains clockwise in the southern hemisphere. Since you actually live in the southern hemisphere could you verify this and let me know? You don't have to if you don't want of course. thanks already for your help above.

LOL - yes it's right, the Coriolis force is a myth of sorts.  It's more related to the initial inertia of the water.  I've recently tested the same, I must've seen the same article!  I've made the water go both ways down the drain :)  Maybe Mythbusters have done an episode on it

Android is most likely the least of your worries as you can install custom keyboards etc.  I've attached the screenshots of my ipad too

That's great. there are a lot more characters than I thought available.

That is good to know about the Coriolis force and how much effect it has on draining water. I don't like to believe things that are not true.

Thanks again for your help.
