boost::filesystem::exists will thought a string is which include zero, is a file, exactly is the file is not exist.

[js1011 <jiangshui584520@…>]

A string like this; std::string path = "/usr/lib/"; path.append(2, 0x0); path.append(3, 'x');

boost::filesystem::exists function will thought this 'path' is a directory.

thanks regards.

Hello,

I have opened a pull-request with the fix here: ​https://github.com/boostorg/filesystem/pull/28

It isn't the job of class path to decide on validity of strings passed to it.

Asian character encodings may have embedded '\0' characters. Shift-JIS is an example, IIRC. If you know the encoding of a string that is going to be used as a path, you could check it for validity before passing it to a path.

Thanks,
