File resource doesn't support CJK file name

I tried uploading same pics with different file names, but failed to display files with CJK characters. Accessing these files returns 502 error.

Supporting these file names could be really helpful.

Thanks for letting us know! We need to fix this indeed. There's currently a pr open that refactors file uploads #659 , there was a bug there relating to file names too. @metame would you mind taking a look if CJK chars work with the refactor?

Yes, happy to take a look at this too @joepio
