Re: [chemclipse-dev] What is the suitable file format for spectrum data

[Trig Chen <trigchen@xxxxxxxxx>]

I used MATLAB 7.10.0 (R2010a) to write and read hdf5 file with chinese filename. The hdf5write() and hdf5read() function worked fine, but hdf5info() ran into error.

Then I used HDF5View 2.13 from HDF Group to open the above file, failed.

The HDF Group have knew this bug. http://hdf-forum.184993.n3.nabble.com/Cross-platform-Unicode-filename-support-tc4028996.html

But it seems this bug would not be fixed soon. Sad for that.

Hi Trig,

please repost this message in the science working group mailing list.


Best,

I found there was a big problem: HDF5 can't correctly resolve the unicode filename in Windows system!

Digging the web, it seems a long time problem. :( .

Is there any workaround  to read or write HDF5 file with UTF-8 filename in Windows system in Java?

Best regards,

Trig

Looks good :-).
Maybe, you could try to use the file extension *.tms.
