Errors when using non UTF-8 characters

What steps will reproduce the problem? (Example)
1. Build and run the youtube video example
2. Enter some chinese characters into the description, for example 这将打破
3. Try to upload the video

What is the expected output? What do you see instead?
This should upload a video with the following description: 这将打破
Error: Error Domain=com.google.HTTPStatus Code=503 "The operation couldn’t be 
completed. (com.google.HTTPStatus error 503.)"

This problem doesn't seem limited to Youtube, the following links are other
