CharsetEncoder for UTF-16 canEncode('\ufffe') is a bug?

[Harald Kirsch]

Hi,

in SUN's bug database I see that canEncode has quite
a few entries recently. By chance I stumbled myself
over this one just now

Charset.forName("UTF-16").newEncoder().canEncode('\ufffe');

returns true. The unicode spec says that FFFE is not
a character, so I would have expected this to be false.

Any ideas?

Harald.

If you disagree with its definition of encodable, you can put a
wrapper around it to deal with your exception.

At least you can fix it. canDisplay is irretrievably broken by
returning true for any no space blob it puts up.
