Re: [Boost-users] [1.35.0][OSX][iostreams] Exception thrown with utf8 filename

I am facing same problem as described below. With a non-english unicode path on OSX, wpath::external_file_string throws. It seems I am missing something trivial like local settings etc, anyone knows whats going on? SG On Fri, Jul 25, 2008 at 6:59 PM, Christophe Radondy wrote:

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, std::allocator >, 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.
