Google cloud speech - does not Python Example ( Streaming ) support multi-language? #487

Regarding Python streaming example ( speech_streaming.py ) ,
when I test it in language "en-US", it works great. but found the alternatives.transcript is not right in case of language "ko-KR".
For example "안녕하세요 안녕하세요" in Korean,
The transcript returned are "[transcript: "\354\225\210\353\205\225\355\225\230\354\204\270\354\232\224 \354\225\210\353\205\225\355\225\230\354\204\270\354\232\224"]
It is not UTF-8.
The python example is not supporting multi-language? or some bug?
Please help me..
