Cannot launch

[GoogleCodeExporter]

What steps will reproduce the problem?

(1) Simply, launch the application.

The following message is displayed and could not run the application:

./src/common/unichar.cpp(66): assert "Assert failure" failed in ToHi8bit(): 
character cannot be converted to single byte

Call stack:
[00] wxFileSystem::URLToFileName(wxString const&) 
[01] wxLocalFSHandler::OpenFile(wxFileSystem&, wxString const&) 
[02] wxFileSystem::OpenFile(wxString const&, int) 
[03] wxHtmlWinParser::OpenURL(wxHtmlURLType, wxString const&) const 
[04] wxHtmlWindow::LoadPage(wxString const&) 
[05] HelpPanel::ShowHelp(wxString const&)

[12] main                                    
[13] start                                   

What version of the product are you using? On what operating system?

Ready-0.5.1-Mac on Mac OSX 10.8.2

Note:
Application built from source (following the instruction in the BUILD.txt file, 
 using wxWidgets 2.9.5 and VTK5.10.1), worked fine on my environment.

Did the prebuilt binary work for you?

I finded out what causes this error.

The problem comes from the directory path name I placed it on the file system, 
which includes multi-byte characters such as Katakana etc.

If it is placed under another directory that doesn't include such characters in 
its path name, it runs without error/warning messages.

(Seems that "wxFileSystem::URLToFileName" (in the above message) can not handle 
multi-byte chars)

OK, thanks for investigating. We need to put some work into making path 
handling more Unicode friendly.

Before you load the path,you should use wxFileSystem::FileNameToURL();
