How to open a file named UNICODE in Windows?

There is a 3rd library only accepting char * filename for example. 3rdlib_func_name(char* file_name)

... Everything goes wrong when I provide the file name in Chinese or Japanese.

Is there a way to make this lib open UNICODE file name? The program runs on Windows .

Thanks for your reply.

We also have a similar problem. Fortunately, there is a solution, although it is quite difficult.

If the file / directory already exists, you can use the function GetShortPathName

. The resulting "short" pathname is guaranteed to contain no non-Latin characters.



  • Call GetShortPathNameW

    (Unicode version) to get the "short" path string.
  • Convert short path to ANSI string (use WideCharToMultiByte

    ).
  • Give the resulting ANSI string for a silly third party library.

Now, if the file / directory doesn't already exist, you might not get its short name. In this case, you must create it first.

No, no, unless you can recompile it from the modified source (basic obligation). You might be in luck if you feed third-party library names with short filenames like AHDF76~4.DOC

; these filenames use ASCII. Cm GetShortPathName

.

You can try to convert the string to a local codepage:

setlocale(LC_ALL,"Japanese_Japan.932");
std::string file_name = convert_to_codepage_932(utf16_file_name);
3rdlib_func_name(file_name.c_str());

Otherwise?

Lock windows for UTF-8 support ;-)
