[Haskell-beginners] Difference between Char and Data.Char modules

I just started looking at the Happy packag; I get a compile error when attempting to build examples/glr/expr-eval:
Could not find module `Char'
It is a member of the hidden package `haskell98-18.104.22.168'.
ExprData.hs:9 says “import Char” and if I change this to “import Data.Char” it compiles correctly (then I get a similar message for System, but when I understand Char I expect I will understand this too).
Could someone kindly explain the difference between these two modules? From the look of the error, I’m guessing there’s a history lesson involved?
