New Public Review Issues: Changes to Character Properties

The UTC is considering some property changes for Unicode 6.2. PRI #227 proposes changes to the Script Extensions property values for certain combining marks. PRI #228 proposes changes of General Category for some common characters from Punctuation to Symbol, to better align with expectations about how those characters behave. Because these characters are quite common, the proposed change may impact a large number of implementations.

For details of the proposals, see the PRI pages:
