Does Boost.Python have translators for boost::filesystem::path and

If not, are there any plans to add this functionality?
There are none in Boost.Python proper currently.
You can find converters for Boost.Fusion in the python_extensions
package in the Boost sandbox; along with Fusion's adapters for
boost::tuple (see the Fusion docs), that should give you what you need:
https://svn.boost.org/svn/boost/sandbox/python_extensions/
You can probably just pull out the header files you want
(to_python/boost_fusion.hpp and from_python/boost_fusion.hpp) rather
than use the whole extensions package. The std_pair.hpp converters in
python_extensions may also be helpful as examples, as they use the
Fusion converters with Fusion's adapters for std::pair.
I also have converters for filesystem::path (just maps to a Python str),
attached - they should probably go in python_extensions, too, but I've
gotten lazy about keeping that current.

I will test the tuple converters.
Concerning path, I need support for unicode paths.
Currently I manually convert from PyObject* to filesystem::path as follows:
BOOST_STATIC_ASSERT(sizeof(wchar_t) == sizeof(Py_UNICODE));
if(PyString_Check(obj))
return path(PyString_AsString(obj));
else if(PyUnicode_Check(obj))
return path(PyUnicode_AsUnicode(obj));
else
... throw some exception ....
This code is not fully portable, but suffices for my current
application. A more robust implementation might use PyUnicode_AsWideChar
instead of PyUnicode_AsUnicode.
