presence of '\ufffd' in resource bundle

Hi

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.

Thanks,
Vijay Venkat

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?
