Variable names not allowed "?" and "!" but method name does - why?

Ruby
1

We can write a method name as foo! or foo?; but not the same with
variable names. Like

foo? = 2

~> -:1: syntax error, unexpected ‘=’

~> foo? = 2

So why such design?

Sorry … I wanted to make sure that the UTF-8 stuff is transported
without alteration of any kind.

I am getting error :-

-- encoding:utf-8 --

a?=5
p a?
b?=8
p b?
c?=false
p c?
