My guess is that the encoding of the file system is set up differently. It needs to match the encoding of the string literals in the C++ source files (and the text editor) to work as expected. In general, you need to translate the encoding from what the program literals or strings have into what the file system is using.

Ive written a small function to copy a directory from one dir to another
When I run this on one Fedora 12 machine, it works fine, even for chinese files and folders.
however, when i run this on Fedora 12 on another machine, it gives me Boost::filesystem::copy_file: Invalid Argument: "/mnt/pd1/??Microsoft Word ??.doc"."/mnt/pd/??Microsoft Word ??.doc"
Why? is the machine missing any package? Please help Here is the code:
#include <iostream> #include <boost/filesystem.hpp> #include <cstdio> #include <string>
using namespace std;
struct dir { int file_count; int total_size; };
void copy_dir(string src, string dest);
int main() {
copy_dir("/media/disk", "/media/disk-1");
return 0; }
void copy_dir(string src, string dest) {
boost::filesystem::path psrc(src); boost::filesystem::path pdest(dest);
if(!boost::filesystem::is_directory(psrc) || !boost::filesystem::is_directory(pdest)) { cerr<<" Source and Destination are not directories "<<endl; }
for(boost::filesystem::directory_iterator i(psrc); i!=boost::filesystem::directory_iterator(); ++i) { boost::filesystem::path from(*i); string to_path=pdest.string() + "/" + i->leaf(); boost::filesystem::path to(to_path);
if(is_regular(from) && !boost::filesystem::exists(to) ) { cerr<<"Copying "<<from.string()<<" to "<<to.string()<<endl; copy_file(from,to); } else if(is_directory(from) ) { if(!exists(to)) create_directory(to); copy_dir(from.string(), to_path); } }
}
