Problem when uploading files with Chinese/Unicode file names

I am testing the 4.0 Dataverse on the 4.0 demo site. I encountered a problem when uploading files with Chinese file names.  (I believe that it is a Unicode problem rather than a Chinese one.) The version 4.0 seems to be not able to recognize Chinese characters in the file name. The files tested were prepared on Mac OS machines. After a file being uploaded, the file name becomes a series of question mark or some other wired characters. It is possible to change the file name back to Unicode/Chinese characters on the metadata web page. However, next time when another file is uploaded to the same dataset, all previously uploaded files with Chinese file names would become problematic again. If I download a file with Chinese file name from the 4.0 demo site, the name of the downloaded file becomes nonsense symbols as well. Please see the screenshot attached. 

Using Chinese file names in my case could be crucial. Therefore, I would be very appreciated if you can let me know your schedule of solving this problem. 

Thank you very much! Great software!

Hi Shih-Pei!

Thanks for the bug report. I believe the bug report at captures the same problem
so we definitely know about it. I'll try to remember to reply to this

Thanks for trying out Dataverse 4.0! Please keep the feedback coming!

Hi Phil:

Thank you! It's good to know that you are tracking this problem already! 

Yes, it is the same bug with the 4061 one, but I believe there is also problem uploading files with international characters in the filename. If you need more information from me, just let me know. 

It's good to get back in touch with the IQSS group! I am missing the spring and summer in Boston/Cambridge!
