You are right that default application tries to use UTF-8 unicode to
communicate with OS, I want to make it use wide-character. Visual
Studio provides an option to choose this for windows, I am just not
familiar enough with OSX/xcode.

The real problem is that wpath::external_file_string() fails on osx.
It throws an exception trying to convert from wchar_t to char saying
'invalid argument'. And I can't track down why.
