Hello, when I try to load images with unicode characters in the file name, it fails. 1static void *file_stdio_fopen(const char *path, const char *mode)
2{
3 FILE *fp;
4
5#ifdef ALLEGRO_WINDOWS
6 {
7 wchar_t *wpath = _al_win_utf16(path);
8 wchar_t *wmode = _al_win_utf16(mode);
9 fp = _wfopen(wpath, wmode);
10 al_free(wpath);
11 al_free(wmode);
12 }
13#else
14 fp = fopen(path, mode);
15#endif
16
17 if (!fp) {
18 al_set_errno(errno);
19 return NULL;
20 }
21
22 return fp;
23}
When I changed the ifdef ALLEGRO_WINDOWS to #if 0 (sing the non-windows variant), it started working, and I could load those files. I'm probably doing something the wrong way, but not sure what is it, I'm no expert of wide string/utf 8. www.factorio.com - a factory building game. |

Then you're probably not providing a UTF-8 path. Sample code?

The part of the filename that contains invalid characteres (User name on windows, while accessing the User/<Username>/AppData/Roaming ... 1boost::filesystem::path Paths::getSystemWriteData()
2{
3 TCHAR szPath[MAX_PATH];
4
5 if (SUCCEEDED(SHGetFolderPath(NULL,
6 CSIDL_APPDATA | CSIDL_FLAG_CREATE,
7 NULL,
8 0,
9 szPath)))
10 {
11 boost::filesystem::path result = boost::filesystem::path(szPath) / "Factorio";
12 boost::filesystem::create_directories(result);
13 return result;
14 }
15 else
16 throw std::runtime_error("Couldn't get application data directory");
17}
Later I just make string out of the path (path / "preview image path").string() and send it to the allegro. You can see, that boost has no problem with creating the directory that contains the unicode character. www.factorio.com - a factory building game. |

.string() returns a std::string, you still need to convert it to a sequence of UTF-8 to pass it to al_load_bitmap() |

Also have to make sure its in UTF-8, rather than the UTF-16 that windows returns. -- |
