Revit will be nice and accept parameter names that include most if not all of them but when it comes time to do something more clever with the parameters you'll regret it. More clevererer? Like using the parameters in a formula, that's clever! You'll get messages like this one.
Easy to resolve, just don't use mathematical symbols in parameter names.

If you really really really want math characters in your formulas, and you dont want to change the formulas you can change the parameter names to include them AFTER you have made the formula.
That's not a strategy with a good future though. :)
Steve I would also suggest the same for family names. Since we can use nested family types in formulas as well now. I am working with a client that used "-" in all fo their family names and now Revit is trying to use thoseas math functions too.
Commas are a bad idea as well - they will get in the way when the parameter is used as a function argument.
If you have a parameter Really cool, too, this will fail: if(Really cool, too, "cool", "not cool").
