It turns out that ifstream::open in MSVC 2005 and later can handle a Unicode
filename directly.

wcstombs() can be used for this, and it seems to be a standard Unix
function.
I've checked in changes to enable FileSource, FileSink, and FileStore to
handle Unicode filenames on Unix and MSVC 2005 and later using the above
methods. Please take a look at
http://cryptopp.svn.sourceforge.net/viewvc/cryptopp?view=rev&revision=472 if
you'd like to review the code.
