Can any one let me know when can a character '\ufffd' get in to a resource bundle.

On trying to figure out what '\ufffd' means - i figured out it means NAN (Not a number in java) - is that correct?

what does the presence of '\ufffd' in a resource bundle signify. I faintly know it is a error and should not be allowed.

Don't know when it happens and how it happens.

Any information on this is higly appreciated.

My understanding...

\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?
