[Boost-users] filesystem and filenames containing "+"

Dear all,

I am experiencing problems with boost::filesystem on files that contains 
a plus (+) sign. Below is a minimal example to test this. the line:

boost::filesystem::path p_plus("filename+.txt");

throws an exception if the filename contains a plus.

Any help or hints would be greatly appreciated.

Best regards,
Simon

output:
*****************
Contents of filename-.txt

"filename+.txt" in path: "filename+.txt"

  return 0;
