Hi,

I try to do a cross-platform source code and I have this code.
I compiled boost 1.35 in universal binaries on Mac OS 10.5.4 with intel platform (IMAC core 2 duo 3Ghz)
The same code works on linux (Ubuntu 8.0.4 and debian) and windows platforms but on Mac OS 10.5 I have an exception in boost's libraries.
We compile on universal binaries with -fexceptions options of g++ 4.0.1 (Apple).

This is my code:
<code>
     boost::filesystem::wpath unicode(L"abcdef\u0110");
     boost::filesystem::ofstream file(unicode.string()); // throws Invalid Argument on Mac
     file << "abcdef" << endl;
     file.close();
<endcode/>

If I do this, it works:

<code>
     boost::filesystem::path utf8("abcdef\xC4\x90"); // \xC4\x90 == \u0110
     boost::filesystem::ofstream file(utf8.string()); // works ok
     file << "abcdef" << endl;
     file.close();
<endcode/>

When the ofstream is created, this function is executed and crashes when I use Unicode parameters :

<code>
     unicode.external_file_string(); // throws

uncaught exception of type boost::filesystem::basic_filesystem_error<boost::filesystem::basic_path<std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >, boost::filesystem::wpath_traits> >
- boost::filesystem::wpath::to_external conversion error: Invalid argument

<endcode/>

Do you have any idea? Is this a known bug? Did I miss a setting?
Thanks for your help.

Regards,
Christophe.
