\fffd is the Unicode 'Replacement Character' - general meaning is you tried to convert a char to Unicode but there was either no mapping, or more than one mapping. So I guess you could consider it "Not A Character" - a bit like NaN, but certainly not equivalent.
In any case, Unicode escapes are processed when loading a properties file so '\ufffd' will be converted to one single Unicode char.
I could be wrong here, though...anyone?
