Can't not upload file name in UTF8

When i upload a nomal file (ascii character), it success.

But when i upload a file with name such as 割 (in utf8)

The response is  400 bad request.

I think the header in httprequest of dropbox api server is accept only ASCII encoding.
Can you fix it?
Thankyou.

Your JSON needs to be encoded in a way that's compatible with HTTP headers.

(E.g. "\u5272" instead of "割")

What programming language are you using? The way to do this varies from language to language.

oh thankyou

I'm using C# but hate that lib httprequest or public lib dll in c#.
I can't show speed upload and request to dropbox server too slow (300-700ms per request).

Then I make httprequest via tcpclient for caculate speed.
