Subject: [ruby-core:46103] Re: [ruby-trunk - Bug #6675][Feedback] Raise exception when convert encoding of a character from GBK to UTF

\ue863 is in the Unicode private use area. Therefore, conversion to GBK 
should not succeed. I get Encoding::UndefinedConversionError just for
    ruby -e '"\ue863".encode("gbk")'

I don't understand why the title of the bug is "when convert ... from 
GBK to UTF-8". The last method call of the test, .encode('utf-8'), is 
quite irrelevant. Justin, can you explain what you want?

Regards,   Martin.
