I port one application from Linux to Windows.
On Linux I use libmagic library from which I wouldn't be glad to rid of on Windows.
The problem is that I need pass name of file that is held in UTF-16 encoding to such function:
int magic_load(magic_t cookie, const char *filename);
Unfortunately it accepts only const char *filename. My first idea was to convert UTF-16 string to local encoding, but there are some problems - like string can contain e.g. Chinese symbols and local encoding may be Russian.
As result we will get trash on the output and program will not reach its aim.
Converting into UTF-8 doesn't help either, because this is Windows and Windows holds file name in UTF-16.
But I somehow need make that function able to open file with Unicode name.
I came only to one very very bad solution:
1. I have a filename
2. I can copy file with unicode name to file with ASCII name like "1.mp3"
3. open it with libmagic functions and get what I want
4. remove temporarily file
But I understand how this solution is bad and how it could make my application slower, so I wonder, perhaps are there some better ways to do it?
Thanks in advance for any tips, 'cause I'm really confused with it.
