Behavior change of Data.Char

Hi,

It seems to me that some characters of GHC 7.10.1RC2 behave
differently from those of GHC 7.8.4:

                          7.8.4   7.10.1RC2
isLower (char 170)        True    False  
isSymbol (chr 182)        True    False
isPunctuation (chr 182)   Fase    True

Is this intentional?

I noticed this because I received a bug report:

As you can see, 167 also behaves differently.
