This was discussed on the May-15 call.
One potential use-case was brought up: that of a user blindly (without checking isSet() that is) setting character values obtained by calling get() on a property of type Character to some other property. That could lead to SDO being unable to save the target DataObject to XML because of the '\u0000' character.
Tentative resolution: 8.1.6 Conversion between Character and String The conversion from Character to String happens when calling getString() on a property of type Character or setCharacter() on a property of type String; the conversion from String to Character happens when calling getCharacter() on a property of type String or setString() on a property of type Character. A Character value maps to a String of length 1, whose first (and only) character is that Character value. The character with the Unicode codepoint '0' maps to the empty String. Strings with length > 1 can't be converted to Character. null String can't be converted to Character.
