is the concept of codecvt_t::partial broken ?

now I don't have the time to analyze the details of this (and it would 
be very difficult without a complete self-contained testcase) but in 
general the current codecvt code works pretty well for us. I would 
suggest: 1- Have a look to the existing testcases in our testsuite, 
which all pass, and see if you can learn something from those about your 
specific case; 2- We may have issues with encoding -1 locales, thus I 
would at first try >= 0 locales. ja_JP.sjis is -1, right?

Thanks,
Paolo.
