No, it isn't ;)

You have to prepare a suited codecvt facet, able to convert during I/O 
from/to
you internal ("in memory") type (unsigned char) to the external ("on 
disk") type
(char): unfortunately, there is no such as thing as a "general" codecvt...

I suggest taking inspiration from the snippet present in our testsuite, 
in particular:

    testsuite/27_io/basic_filebuf/seekoff/wchar_t/12790*.cc
    + testsuite_character.h
