Mat_CreateVer and Mat_Open do not support unicode (wstring) filename on windows

Mat_CreateVer and Mat_Open do not support wchar_t* as filename

A = 1:10
save('d:/漢字.mat')
clear
load('d:/漢字.mat')

Confirmed. Unfortunately, there neither is a wide-tring equivalent of H5Fcreate nor H5Fopen. Please see also here or contact the HDF Group with your requirement. Once the hdf5 C library supports wide-string file names, I can extend matio to also support it consistenly.

not only hdf5, same problem with v6, or others

I know. That's why I wrote consistenly = for all versions.

reported on HDF5 forum: https://forum.hdfgroup.org/t/h5fcreate-and-h5fopen-with-chinese-filename-wide-char/1450/5 and here: https://forum.hdfgroup.org/t/wide-string-equivalent-of-h5fcreate-or-h5fopen/5482/2

Should be possible by 6d47ebd4bb1186a737f895848009de1e317f9962. For v7.3 MAT files you'll need the next major HDF5 version (probably 1.12.x due in September).

By the way, it already was working correctly in Cygwin, but I guess you meant MSVC when you said windows.

It will be available in 1.12 current branch is only alpha stage ... https://bitbucket.hdfgroup.org/projects/HDFFV/repos/hdf5/browse/release_docs/HISTORY-1_10_0-1_12_0.txt?at=refs%2Fheads%2Fhdf5_1_12

Yes, there is not yet a released hdf5 library version.

hdf5 1.12 is available. A matio release with official support could be great. It seems that vs project (matio) need to be updated (zlib.h not found) for hdf5 1.12 but zlib.h is available in CMake-hdf5-1.12.0-x64\build\ZLIB-prefix\src\ZLIB
