[Boost-users] Boost.Filesystem -- bug or user error?

   I'm using Boost.Filesystem (along with Boost.Regex, and an unofficial glob library by 
Angus Leeming) to do globbing and batch file processing in a utility of mine. Environment 
is boost_1_32_0, Windows XP, MSVC++7.1. The Glob/Regex stuff seems fine -- I fill a 
vector<string> container with the results and then pass it off to another piece of code to 
actually do the work.

   Part of the work involves printing the filename (without path, but with extension). 
Here's a snippet:

int ProcessFile(ofstream &Out, const char *FullPathName)
{
int Success = 0;
fs::path OutFilePath(FullPathName, fs::native);

std::string JustName, NameNoExt;

JustName		= fs::basename(OutFilePath.leaf()) + fs::extension(OutFilePath.leaf());
NameNoExt	= fs::basename(OutFilePath.leaf());

PrintItem(Out, FullPathName, JustName.c_str(), NameNoExt.c_str());

return(Success);
} // ProcessFile

   Ignore that it's poor code quality -- this is just a quick & dirty hack program.

   Everything works great until this code is fed a FullPathName of:
eggs+butter01d-thumbs.jpg

   (In this example, I'm running with relative paths, so there is no "path" part to 
discard. Makes troubleshooting even simpler.)

   It throws an exception of
boost::filesystem::path invalid name eggs+butter01d-thumbs.jpg in path 
eggs+butter01d-thumbs.jpg

   on line 341 of path_posix_windows.cpp

   It appears to displike the + character.

   Maybe it's pilot error, but + is apparently a valid symbol in the Win32/NTFS 
filesystem, and Windows permits it, generally. If it were a weird platform-specific 
symbol, I would have thought that creating the fs::path with

fs::path OutFilePath(FullPathName, fs::native);

   would have translated it into somethign boost-friendly.

   Anyone care to tell me what I'm doing wrong? Thanks in advance for any advice.
